centuries

We have had a nautical chart for almost two centuries in a drawer because we thought it was all wrong. we were wrong

by

Sometime in 1835, on the northwest coast of India, Alexander Burnes purchased a roll of paper. Inside was a handwritten navigation chart of the Red Sea and the Gulf of Aden that the British officer came to describe as a “specimen of naval survey without equal in the cabinets of Europe.” Burnes donated it to the Royal Geographical Society, where a team of experts examined it and put it in a drawer. Since then, the diagnosis has been unanimous: the letter was very beautiful and very attractive, but completely wrong. For 189 years, we have believed it was wrong. But we were wrong. And it’s not that we hadn’t studied it. In the last century alone it has been studied in detail on up to five occasions (1947, 1987, 2002, 2012 and 2022). However, all efforts had been futile. However, in recent years, John P. Cooper of the Institute of Arab and Islamic Studies at the University of Exeter and his team They have studied the subject in depth. Without much success, really. Until they realized one thing: what if instead of a document, what they had in their hands was a tool? I mean, what if it wasn’t a map to hang on the wall, but something else? How did the thing work? The key, always according to the researchers, is that the letter was only opened to the section that the navigator was using at that time. If you look at the map as a whole (more than 180 islands, plus reefs, land landmarks, religious buildings and flags), you don’t understand; above all, because they do not have continuity. But if you analyze the references fragment by fragment, the idea emerges that it was used to maintain the navigation line, to remind the sailors what they had to do. Its purpose was mnemonic and operational; not representative. How curious, isn’t it? Yes and that is the main problemto think that all this is just ‘curious’. But no, what the letter puts on the table is the Eurocentric bias that still prevails in the history of science: For almost two centuries we judged an Indian tool by the only yardstick we knew (the geometric correspondence to the terrain) and declared it “defective” for not meeting that yardstick. How many thousands more things will we have out there lost, without fully understanding? It never hurts to remember that there are many things that we do not fully understand.

archaeologists have hacked their way to a Mayan city hidden for centuries in the jungle

by

They have baptized him ‘Minanbe’ (“there is no way”in Yucatecan Mayan) and the truth is that few names would better describe the pre-Columbian site that archaeologists have just discovered in the middle of the Campeche jungle, in Mexico. After traveling kilometers and kilometers using machetes and with the help of quadsunder the scorching sun of the Yucatán, a team of researchers led by the Slovenian Ivan Sprajc has reached a mayan city forgotten that, according to its first observations, must have played a relevant role during the Late Classica period spanning 600 and 900 AD Then the jungle devoured the settlement for more than a thousand years, a long period of oblivion that has just ended. What has happened? It is not strange that the National Institute of Anthropology and History (INAH) of Mexico stirred the waters of pre-Columbian archeology with important discoveries. In recent years, however, there have been few as fascinating as the one just presented in Campeche. And not only because of its reach. The location and intra-history of the discovery of the ancient Mayan city of Minanbé is so surprising that two facts are known to understand its scope: it took more than a decade of work and traveling several kilometers of jungle to reach it. Why’s that? Because Minanbé was in an inaccessible place. And in this case we can use the word with all of the law. The city was “camouflaged among the jungle tangle of the Calakmul Biosphere Reserve,” in words from INAH itself, who remembers that the archaeologists and technical staff of Ivan Šprajc’s team found it so difficult to get there that they decided to name their discovery with two words from the Yucatecan Mayan: mina’an (“there is not”) and bej (“path”). For good connoisseurs there are too many words. To reach the old settlement, located in Campeche, they had to make their way as best they could. First they traveled along an old forest path, advancing aboard quads. When the jungle became too thick for these vehicles, they had no choice but to advance on foot, clearing brush with the help of machetes and sinking their boots into the mud. “They opened a gap with the edge of a machete for five kilometers,” precise the institute. How did they know it was there? With the help of technology. Archaeologists identified the ruins thanks to aerial scans made with LiDAR, a tool which allows researchers to identify constructs impossible to observe at first glance through the vegetation. The first clues were actually obtained more than a decade ago. “In this field season the team once again entered the northern sector of the reserve to carry out a superficial survey of a site west of Chactún, a governing center reported by this same initiative. 13 years ago and for which they had airborne laser scanning (LiDAR) data,” explains the INAH. The images showed a settlement of about 15 hectares, but the most complicated task remained and has now finally begun: verifying these indications “at ground level.” A lot of causality, right? That experts were scarce in that area of ​​Campeche was not a coincidence either. Šprajc, attached to the Research Center of the Slovenian Academy of Arts and Sciences, has been dedicated for decades to the study of the Central Maya Lowlands, “a fossilized archaeological landscape that was the habitat of between nine and eleven million people during the Late Classic period,” recalls the INAH. The truth is that Šprajc I intuited that the jungle could hide an undiscovered treasure. To begin with, there were no roads leading to the ruins. Not even the dirt trails opened by the logging industry decades ago. And although that complicated the team’s mobility, it was also a “good sign.” “Compared to other places where we have done surface tours, access here was much more difficult. However, in the last three years it is the first site we found intact. “There are no looting coves,” adds the researcher Slovenian. “It was a big surprise.” What is Minanbe like? If there is another word that defines Minanbé, besides “inaccessible,” it is “promising.” When the team arrived at the site they found “an urban nucleus” with squares, palatial and religious buildings, terraces and hydraulic pipelines. The ‘jewel in the crown’ is a pyramid-shaped temple more than 13 meters high and a style reminiscent of the architecture of Río Becidentified in dozens of sites and which is distinguished, among other things, by the complexes with towers. The experts stand out especially its masonry and the smooth panels of the dated, a steep staircase and moldings. Vitan Vujanović, one of the participants in the expedition, recognized It was recently the first time that he had the opportunity to record “a more or less well preserved temple and a stele still with glyphs.” One in particular stands out that represents a decapitation scene. Do we know anything else? Yes. The researchers took hundreds of photographs that have allowed them to create three-dimensional models of 14 altars and stelae, including the piece that shows how one individual wields an ax to decapitate another. These recreations help us decipher the engravings despite the erosion and have shown that this particular stele has a temporal reference that places it in 849 AD. “It is an important key because we can think that the entire set of monuments or some were erected for that moment of the Terminal Classic, close to the abandonment of the sites in the region, which happened in the 10th century AD,” comment another participant in the project, Octavio Esparza. The monuments have led experts to two other conclusions. First, Minanbé could have been an enclave with some political powernot a minor city. Second, over time groups from outside were able to arrive in the city and deliberately alter some monuments.

Centuries ago someone thought it was a good idea to paint over a Rembrandt painting. The question is why the devil erased a man with a turban

by

The fact that he has been dead for more than three and a half centuries does not prevent him from Rembrandt Harmenszoon van Rijnone of the great geniuses of baroque painting, continue to surprise historians. And in the most unexpected ways. In 2014, one of his youthful works appeared by surprise at an auction held in Cologne. Now, with your attribution already confirmedthe experts in charge of cleaning the canvas have had another surprise: under a subsequent layer of paint they have discovered a man with dark skin, a black beard and a large turban. It was once painted by Rembrandt himself, but someone decided to retouch the figure to turn it into a venerable old man with a white, wrinkled face, gray beard, and a traditional Dutch cap. The question is obvious: Why? Isn’t that a Rembrandt? The painting Let the children come to me It was probably painted around 1627, when Rembrandt was 21 years old. However, it did not rise to fame until almost 400 years later, well into the 21st century. To be more precise, we must go back to May 2014, when the canvas was included in an auction held in Cologne with a fuzzy business card. Its owners presented it as a piece of the “Dutch school” dating back to the mid-17th century and sold it for 1.5 million euros. It was a good pinch, but it ended in pocket change when some time later it was confirmed that in reality that anonymous 125 x 109 cm canvas (with frame) was neither more nor less than a work from Rembrandt’s youth. Recently Sotheby’s he put it up for auction again with an estimated value of between 9.3 and 14 million of euros. The work before the restoration, with the added modifications. And the (other) surprise arrived. Such a record would have been enough to give the painting a prominent place in Rembrandt’s legacy. Recently, however, Sotheby’s revealed that the canvas hid another secret. What we have seen so far was not exactly what the Leiden artist painted, but rather a version adulterated by a hand less skilled with brushes, a contemporary artist by Rembrandt. There are those who even have a name: Claes Cornelisz Moeyaert. Given that experts believe that the Dutch painter left the work “partially unfinished”, working hard on the upper part of the painting and sketching the lower part, it is understandable that someone would want to finish it. The intriguing thing is that in doing so that anonymous hand did not simply follow Rembrandt’s design. In addition to finishing the canvas, he repainted it, erasing, adding and modifying it to taste. We know this because in recent years technicians have studied the work with X-rays and have dedicated themselves to carefully eliminating overlapping layers. Does things change that much? Yes. It comes with taking a look at the photos that were released on the day of the painting and those disclosed by Sotheby’s following the last auction to prove it. The motif of the painting is the same: the biblical scene, collected in the Gospels of Mark, Matthew and Lucasin which Jesus uttered his famous phrase: “Let the children come to me.” If we look closely, however, differences can be seen between its status in 2014 and 2026. The elimination of the repaintings changes the color, has made some figures emerge and eliminated others. A boy in the foreground who was wearing an ocher suit now looks how Rebrandt must have seen him, with his back bare. However the most powerful alteration It is another: we now know that one of the central figures in the scene was a dark-skinned man with a turban who the artist who retouched the work completely modified, turning him into a venerable old man. For some unknown reason, the original exotic turban ended up becoming a red Dutch hat and the black beard became a long, gray beard. The work already restored and as presented by Sotheby’s. More than a detail. That detail has attracted attention of media from half the planet. And it’s normal. There are those who believe that if Rembrandt initially opted for a man with a turban, surely Muslim, it was not for an aesthetic reason. He wanted to capture what he saw in part in his own country in the 17th century, a multicultural environment, marked by religious rivalries, the coming and going of thousands of refugees and the social tensions that this generated in the streets. As remember historian Andrew Graham-Dixon, “in 1627, when Rembrandt began the painting, Leiden was going through a humanitarian crisis.” “The Thirty Years’ War was at its peak and hundreds of thousands of people arrived as refugees in the Dutch Republic,” he adds. It is estimated that in 1626 alone approximately 10,000 refugees arrived in Leiden. …and more than paint. Was that context transferred to Rembrandt’s canvas? Did you want to capture the spirit of what you saw on the streets of your city, the position that in your opinion should be maintained towards refugees arriving from other places? “It depicted a mass scene of Christ welcoming children and families. It was very controversial at the time. There were people in Leiden who did not want to receive them,” Graham-Dixon abounds. “What we gather is that Rembrandt was on the side of humanitarian aid. So I think this is more than just a painting. It’s a statement of his moral stance.” The truth is that in the work we see a crowd in which religion is represented. Jewish and Christian. “It looks familiar”. The figure wearing a turban is not the only surprise. Experts have identified in it a self-portrait of Rembrandt himself, who represented himself at the top, as a young man who appears to be looking at the scene perched on a pillar, although in reality he is looking at us. “His physiognomy is familiar to us thanks to the numerous painted self-portraits, drawings and engravings that he made over … Read more

Centuries ago, the merchants of a town in Segovia decided that no one would understand them. They ended up creating a unique language

by

It does not reach 3,700 inhabitants and it is almost an hour from Segovia capital and 90 minutes from the center of Madrid, but Cantalejo (Castilla y León) hides a fascinating treasure, one of those that cannot be valued in euros or any other currency. For centuries this small town in the Duratón region has been the epicenter of a unique dialect: the gallerya jargon once used by threshing floor merchants and which, according to some experts, draws on words taken from other languages, such as Basque, Galician, French or Arabic. Now he keeps a pulse so as not to disappear. What is the gagaría? The “jargon of the Cantalejo thrillers.” Or at least this is how he defines it the ‘Dictionary of Current Spanish’ of the BBVA Foundation. However, to fully understand the history and relevance of the gacería (or briquero) more nuances must be taken into account. Its richness of lexicon means that it is often presented more as a ‘dialect’a ‘linguistic variant’ or even a language. Its use has also transcended artisans and threshing floor merchants to extend to other areas. Nowadays there are websites where is documented the vocabulary and expressions of the slang and even published works in the slang, including a hobby book and a translation from ‘The Little Prince’ by Antoine de Saint-Exupéry, whose briquero title would be ‘The cocky pitoche’. Its footprint also expands beyond the municipal area of ​​Cantalejo, with echoes in other neighboring towns in Castilla y León. More than 300 words. As Professor Sara Engra explains in an article On the subject, the gazería presents some interesting peculiarities. At a linguistic level, in terms of word structures and intonation, it conforms to Spanish norms. Also its syntax. What differentiates it is its lexicon. “It is limited to replacing Spanish words with (mostly) borrowings from other languages,” explains the linguist, who gives as an example ‘The gazebo is garnished by the briqueros of Vilorio Sierte’which would be translated as ‘The gacería is spoken by the inhabitants of Cantalejo’. The structure of the sentence, the use of verbs or plurals is similar to Spanish, the lexicon changes. What makes slang so amazing is your vocabulary and how you have formed it. The web Cantalejo.comwhich is dedicated to collecting words and disseminating the characteristics of speech, assures that the briquero is made up of 353 terms, almost all nouns, although there are also 40 verbs and a handful of adjectives, such as ‘serte’, ‘gazo’, ‘pitoche’ either ‘sievo’which in Spanish mean, ‘good’, ‘bad’, ‘little’ and ‘old’. Other sources raise their lexicon to about 500 words. From Basque to Arabic. Beyond its greater or lesser richness of vocabulary, the most striking thing about the gacería is the origin of those more than 300 words that make up its slang. Engra remembers that there are terms from Basque, Galician and Catalan, but also others imported from Arabic or even Galicianisms. The linguist specifies that in some of the words of Cantalejo’s slang another phenomenon can be seen: metathesiswhich basically consists of changing the place of one or more sounds or syllables of a word, as may be the case of ‘miraglo’ instead of miraculo or ‘murciégalo’ for bat. If we review the lexicon of the gacería we can see that there are terms that derive from Spanish through this ‘deformation’. It is not his only strategy for creating words. Another, just as interesting, is to recover rarely used words and use them to indirectly refer to a new reality. Engra cites a specific case: significant (“carrying a sign”) is changed to ‘sinifaro’which means ‘civil guard’. Other peculiarities of speech are its intonation and gestures. The origins. The authors do not always agree on the details of the origin and antiquity of the gacería, although they do tend to agree on several details. The first, which dates back centuries. The second, the key role played by the inhabitants of Cantalejo who traveled through Spain to sell threshes and cattle. Engra, for example, slide which served as a code, a ‘secret’ speech shared by the Cantalejans that allowed them to “encrypt conversations and hide information” when negotiating with merchants from other regions. The gaceria would therefore be like a code created and nurtured by the residents of Cantalejo who traveled around Spain to trade their goods. When they wanted to exchange information with each other, safe from other people’s ears, they resorted to their own jargon that was indecipherable to merchants from other areas. Regarding its origins, it is usually pointed to 13th centuryalthough there are who points rather to the 16th, 18th or 19th century, with its peak well into the 20th century. a living speech. “When our ancestors toured Spain and went through Galicia, the Basque Country, Extremadura… they heard different dialects, words that they did not understand, so they brought many of them with them. In the workshops they were later unified, forming phrases. And thus the gacería was born,” explains to The Newspaper Ana Rosa Zamarro, mayor of Cantalejo and leading voice in the defense of slang. “They used it to warn each other during sales deals.” With the changes in agriculture and the depopulation of rural areas, the gacería has been losing ground, which does not mean that Cantalejo has forced its speech. A jargon for the 21st century. Zamarro assures that continues to be heard on the street and in recent years steps have been taken to guarantee its future, which includes since the publication of hobby books or to the translation of classic works. Even the local public school works to pass it on to the new generations. The objective: that Cantalejo (and the province of Segovia and Castilla y León) does not lose one of its great linguistic treasures.

We have been reading the Bible as a moral guide for centuries. More and more people use it for something else: looking for investment funds

by

When one puts your savings (many or few) in investment funds what you want are good returns. May your money generate more money. The question is… When pursuing this objective, can any criteria be applied beyond the strictly economic one? Is the search for profitability compatible with a moral approach? There are people who believe that the answer is ‘yes’ and that the financial sector must grow with an eye on environmental ethics or social, what happens, for example, by not supporting polluting companies. In that line, more and more people He decides to put his money in another type of investment funds: those that combine the search for profits with the morality of the Catholic Church. Investments and ethics? Exact. Although investment funds and exchange traded funds (ETF) are tools created to generate money, part of the financial sector has been trying to manage them with an ethical approach. Their idea is very simple: they offer returns, but with the guarantee that their analysts will be as attentive to the stock market as they are to the ESG criteria (Environmental, social and governance). That is, the idea is to bet on companies that in theory apply good practices and are respectful of the environment. What about religion? Among these ‘ethical’ funds, not all of them focus on respect for nature or human rights. There are those who emphasize the spiritual. His idea is that money generates profitability thanks to companies that conform to the precepts of a religion. Said this way, it may sound very abstract, but in practice it is very simple: investors avoid companies that make money through pornography, contraceptives, gambling, drugs, child exploitation, weapons, stem cell research… A clear example is the ‘Islamic EFT’funds that operate with sharia on the one hand, betting on companies that comply with the laws of the Koran. Does it happen with Christianity? Yes, too. In fact, just a few months ago, in februarythe Vatican Bank launched two stock indices that aim to make it easier for those who want to invest their money with a Catholic mentality. To be more precise, the Institute for the Opera of Religion (IOR) presented the Morningstar IOE Eurozone Catholic Principles and Morningstar IOR US Catholic Principles, a sort of S&P 500 and Euro Stoxx 50 ‘Vatican version’. “Both benchmarks are developed following best market practices and in accordance with Catholic ethical criteria. They are designed to serve as a reference for Catholic investments around the world,” explains the IOR. In the case of the European index are included for example, the banks Santander and BBVA, the technology company ASML or the luxury firm Hermes, while other multinationals with defense subsidiaries or presence in the alcohol market are relegated. In the case of the USA, Meta or Amazon appear. But… Do these funds move money? Yes. We know it thanks to a recent analysis of Five Days which confirms that Christian funds are strengthening their footprint globally. And clearly, too. The latest report from the consulting firm Brightlight shows that in the last five years alone they have doubled their assets, going from just over 58.5 billion dollars in the summer of 2020 to more than 115,700 million at the end of September 2025. If we look further back, funds based on Christian principles barely accumulated an asset of 16.5 billion in 2009 or 1,500 in 1990. What do they invest in? The increase in variable income assets stands out above all, followed by fixed income assets. In total Brightlight has identified 166 funds Christians, which is also double the number recorded in 2010. Such an increase is not explained only by the launch of the two indices of the IOR in February. Much earlier, in 2022, the Church already published Mensuram Bonama document with “a set of principles and criteria” aimed at the financial sector. “Investors are increasingly looking for benchmarks that reflect specific value- or policy-based criteria,” defend Morningstar. And how are they doing? Not bad. Although in general investment funds that are guided by ESG criteria have not gone through his best moment (last year they saw capital outflows worth more than $80 billion), the S&P 500 Catholic Values ​​Index has located above of the S&P 500 in recent years. Nothing surprising, moreover, if we see the list of companies on which it focuses. The growth of funds with a Christian focus can be explained, beyond the drift of the stock market, by their own characteristics. Some, for example, donate a part of their commissions to entities linked to the Church.

In Asia they haven’t put ice in the water during meals for centuries. Digestive physiology just explained why they were right

by

The other day a friend told me about a peculiarity she observed during a recent trip to China: the glass of ice water on the table is almost a rarity. Instead you’ll find a pot of green tea, a bowl of broth, or just nothing cold. For centuries, in much of Asia, drinking cold liquid during a meal has been an eccentricity more typical of the West than there. What for a long time seemed like a quaint custom, or directly a matter of infrastructure—ice was not always available everywhere—turns out to have a pretty solid physiological explanation. The temperature of the water we drink while we eat is not a minor detail. It affects the movements of the stomach, the rate at which it empties, and how the muscles of the digestive system behave. And science, although with important nuances, is beginning to agree with what millions of people in Asia have been practicing for millennia. Before getting into the physiology, we must understand how this debate has reached the West. It has not been through a medical congress or a scientific journal. It has arrived, like so many other things, through TikTok. The phenomenon is known as chinamaxxing either Becoming Chinese: a viral trend in which thousands of Western people adopt lifestyle habits from Chinese culture, including drinking hot water. According to documents The New York Timeshot water has become “the new superstar of online well-being”, with influencers documenting how this habit deflates them, gives them energy and improves their digestion. But what the Internet presents as a revolutionary discovery is nothing new. This practice has been rooted for thousands of years. in Indian Ayurveda—where the morning ritual of drinking hot water is known as usha paana— and in Traditional Chinese Medicine, where cold is believed to “turn off the agni“, the digestive fire, and weakens the vital energy or Qiforcing the body to expend extra energy to warm the stomach. Hot water, on the other hand, balances the Yin and the Yang and keeps the body calm. Just because something is part of an ancient tradition does not automatically make it scientific truth, of course. But it doesn’t disqualify him either. The question is what exactly science says when it begins to analyze what happens in the stomach according to the temperature of what we drink. What really happens in the stomach? To understand the debate, we must separate two things that are often confused: the effect of drinking water during a meal and the effect of the temperature of that water. They are different questions with different answers. On the one hand, regarding water itself, there is a widespread belief that drinking water during meals dilutes gastric juices and digestive enzymes, slowing down digestion. Medical portals such as HealthLine They explain that there is no solid scientific evidence that water dilutes gastric juices or significantly hinders digestion. The stomach has a dynamic regulatory system that detects changes in pH and automatically secretes more hydrochloric acid to compensate. Drinking a glass of water during a meal hardly alters that balance. Marina Domene, head of nutrition at SHA Spain nuances in Vogue Where is the real limit: the problem is not drinking water, but excesses. “What is not recommended is drinking excessive amounts, more than two or three large glasses, as it could distend the stomach too much and temporarily dilute the enzymes,” he explains. It also points out that there are specific contexts where it is advisable to be more careful: in people who suffer from hypochlorhydria – low production of stomach acid – it is not recommended to consume liquids during meals. On the other hand, regarding temperature the panorama changes and this is where physiology begins to agree with Asia. The temperature of the liquids directly affects gastric motility, that is, the muscle movements of the stomach that drive digestion. Domene explains it clearly: “Cold drinks can slightly slow down gastric emptying and constrict the blood vessels of the stomach, which in sensitive people can be heavy. Hot liquids, such as broths or infusions, have a relaxing effect on the smooth muscles of the stomach.” This is not just a clinical opinion. There are studies that support this, such as research on the effect of temperature on gastric emptying have observed that very cold drinks, around 2-5 °C, can temporarily slow down the initial phase of gastric emptying compared to liquids at body temperature. Drinks at 4°C also disrupt antral and pyloric contractions, briefly retaining stomach contents. An experiment with 11 young men who consumed 500 ml of water at different temperatures found that water at 2 °C reduced the frequency of gastric contractions compared to water at 60 °C, and that lower muscle activity was related to lower subsequent caloric intake. The sample sizes of these studies are modest—it should be said—but their results consistently point in the same direction. A study published in Gastroenterology Nursingfocused on patients who had recently undergone colon surgery, observed that the consumption of hot water had a positive impact on subsequent bowel movements. It is not a study designed for healthy people, but it adds evidence about the role of temperature in intestinal motility. Gastroenterologist Dr. Lisa Ganjhu, consulted by The New York Timesdescribes it more graphically: during the night, the digestive system slows down. Hot water generates waves of contraction and relaxation in the muscles of the esophagus, stomach and intestines. “It’s basically telling everyone, ‘Okay, get up. We’ve got to get going,’” he explains. Why did they take that path and not another? The physiological explanation that science offers today connects quite well with what traditional Chinese medicine and Ayurveda have been saying for centuries, although in completely different languages. In China, Japan and much of Southeast Asia, It is common to accompany meals with hot tea or soup. It is not a fad or a recent trend: it is part of the structure of food. The broth does not close the menu, it accompanies … Read more

For centuries Spain shone for its castles. Today we do not know exactly how many there are and we have thousands that are increasingly dilapidated

by

There are times when the best way to raise awareness is to take out a cell phone at the right time and place. Occurred a few weeks ago in Escalona, ​​Toledo, when one of the tourists waiting to enter the castle of the town observed that stones were beginning to fall from one of the towers. His impulse was record the scenewhich ended up immortalizing the mere five seconds in which the structure crumbles in a cloud of dust, taking with it centuries of history. The video ended up going viral and leading to another debate: the conservation of the castles of Spain. At the end of the day Escalona It is not a unique case. Two collapses in one year. Escalona Castle is a stately fortress whose history can be traced back to Roman times and covers a period that extends from the 1st century AD to the 12th century. Neither that, nor its status as BIC, nor the City Council’s plans to restore part of the structure prevented two months ago, March 14the albarrana tower will collapse in front of a tourist’s camera. the castle Almonacid of Toledo It is also another heritage jewel of Muslim origin whose chronicle dates back to at least 848. Again, neither that antiquity, nor its enormous historical wealth, nor its protection like BIC prevented one of its most emblematic towers from would fall apart after several weeks of heavy rain. “We have reached this situation because they (the Board and the owners) did not spend a euro on historical heritage. In the end what we feared has happened: it has fallen,” explained the councilor, Almudena González, to The Country. @latinus_us Tourists recorded the moment in which the tower of the Escalona Castle collapsed, in Toledo, Spain; there were no injuries. The site dates back to the 11th century and in 1922 it became a Site of Cultural Interest. #Latinus #InformationForYou ♬ original sound – Latinus – Latinus How is it possible? That’s it the debate that began to gain strength after both events, especially because both occurred in a surprisingly short period of time, not far away and affected fortresses with high historical value. Added to that is the viral video of Escalona. The truth, however, is that both news have stirred up a problem that is by no means new. Although the vast majority of castles in Spain enjoy heritage protection since 1949in practice the state of conservation of the thousands and thousands of fortresses that are distributed throughout the Spanish geography is very “unequal”, as explains Miguel Ángel Bru, member of the Spanish Association of Friends of Castles (AEAC), to the SER. Do we handle data? Some. And they paint a scenario that clearly could be improved. In the same interview in which he was asked about the heritage of Castilla-La Mancha (where Escalona and Almonacid de Toledo are located), Bru provided a revealing percentage: only 20% of the castles have been rehabilitated and are maintained in an acceptable state. The remaining 80% present more or less serious conservation problems. Another interesting approach is provided by Hispania Nostra, an association that is dedicated to the defense of Spanish heritage and is known above all for its “Red List”which includes those elements “threatened by a serious risk of destruction, disappearance or irreversible loss of their heritage values.” If we search for “Castles and fortified architectural complexes” we obtain dozens and dozens of results spread throughout the country. And the selection increases if we include other types of structures, such as “forts, military buildings, towers or walls.” The percentage: 60%. Probably the most shocking fact was shared a few days ago by Bru on a talk with The Country in which he warned precisely about the state of conservation of a large part of the heritage: “Six out of every ten castles in Spain are exposed to collapsing, but if we refer to smaller landslides, partial falls, we would already be talking about eight out of ten.” In reality, the problem is not only that it is estimated that 60% of the fortifications are in conditions very far from what would be ideal. The real challenge is that we don’t even have a complete, closed ‘photo’ of how many structures there are. “The first catalog there is is from 1968, it is the one recognized by the Ministry of Culture, but it is completely insufficient because the number of records is very low,” duck the director of the AEAC. To solve this, the association has been developing for decades a list of defensive structures that already exceeds 10,000, but that does not mean that the study has ended. If we want to protect the castles, the first stepEssentially, it is to have a precise idea of ​​how many fortifications exist. The other figure: 2,807. Right now the catalog of Castles of Spain includes a total of 10,362 registered properties. That is the global figure, the most updated photo that the association has achieved. When we go down to detail, however, we obtain other more worrying ones. Of those 10,362 castles, only 728 They are in “very good” condition. 2,209 They are considered to be in good condition and 1,037 They are in a situation that technicians consider “regular.” In 537 cases the collective speaks of “consolidated ruins” and in 2,087 of “progressive ruin.” The entity contemplates still other scenarios, such as fortifications that have already disappeared or that have been altered. The big question: Why? How is it possible that, despite their high heritage, historical and even tourist value, and that they are protected by state regulations, there are so many castles with poor conservation in Spain? There are several factors that come into play. One is that not all buildings play the same cards. There are large historical complexes located in populated areas that have become symbols ‘pampered’ by the administrations. And also isolated fortifications or in rural areas that have not suffered the same fate. If we talk about … Read more

How the Black Death caused Europe to become obsessed with the act of sneezing for centuries

by

Hebrew tradition tells that, just before biting the apple, Adam sneezed. At that moment it seems that he didn’t care much, but after the incident with the fifth piece of fruit a day he ended up interpreting it as “a sign of evil and a harbinger of death.” The noise stayed there, of course, and when the very old Jacob was worried about not getting to see his son, he begged God to change the natural order of things lest a bad sneeze take him to the other neighborhood. That’s where it comes from (collected or perhaps invented anew by medieval tradition) that we desire “health” in Spain, “saúde” in Portugal or “Gesundheit” in Germany to someone who has just sneezed. As if to ward off bad omens; that life is not enough to play with dice. However, because it is common, I still find it surprising how much a simple sneeze has come to mean. Aristotle, explains García-Morenowas convinced that, compared to flatus or belching, the sneeze was the only one that had a ‘sacred nature’ because it came “from the main and deepest and most divine of the organs, the one that contains the spirit.” Hippocrates, on the other hand, although he did not decide on the goodness or badness of sneezing, he did describe the principle of reciprocal inhibition by pointing out that sneezing was, mind you, the best remedy for hiccups. As I said, the history of sneezing in the West cannot be understood in all its complexity without the Black Death. It was then that the “health” of the Jewish tradition or the “Jesus” of the Christian tradition became popular again as a way of wishing that this ‘achís’ was not the doorway of the damned plague. The “God bless you” that still resonates in English formulas (‘bless you’) comes, it seems, from one of the many plagues that struck medieval papal Rome. In contrast, in many other places, sneezing was considered a good thing. Fantastic. Traditional Hindu medicine used to provoke it as a way to balance internal humors and treat illnesses while the more archaic African medicine used it protopsychiatrically as a way to cure mental illness (supposedly caused by the existence of worms in the brain). To finish, to finish at some point, the Aztecs used it for headaches. What is a sneeze really? In reality, a sneeze is something very simple. It is a reflex actionsudden and compulsive, whose purpose is to expel large amounts of air through the nose and (sometimes) also through the mouth. It is, therefore, a physiological reflex that the respiratory system uses defensively. Therefore, it usually occurs when certain foreign particles irritate the nasal mucosa. And yes, I have used “usual” with all the intention in the world. As it seemsand these are average estimates, before each sneeze we inhale about two and a half liters of air. That is the first phase, the inhalation phase. At that moment, the abdominal muscles tense the diaphragm to increase the pressure in the lungs and force the air to come out through the nose at dizzying speed: between 70 and 130 kilometers per hour. The saliva that is usually expelled when sneezing can cover an area of ​​up to 8 square meters. And that is precisely what makes a sneeze one of the worst vectors of disease spread in the world. However, sneezing is most popular precisely when it is most harmless: in spring, summer or autumn. When it is caused by ‘allergic rhinitis’. A classic, indeed. This type of rhinitis, caused by pollen from trees, weeds and grasses, becomes the great recurring character in the lives of practically a third of the population. It is unbearable, unbearable, a cross. But, still, there are worse sneezes. Between 18 and 25% of the population sneezes suddenly when exposed to bright light. This is what is known as ‘photic sneeze‘and it’s an old acquaintance (and a cause of disability) of aviation pilots. Apparently it is hereditary and is produced by an anatomical proximity between the second cranial nerve (the ocular, responsible for carrying visual information to the brain) and the fifth (the trigeminal, which seems to be responsible for sneezing). When there is very bright light, excitation of the optic nerve can cause excitation of the trigeminal nerve. This signal is interpreted as irritation of the mucous membranes and releases a beautiful, annoying and enormous sneeze. Something similar (although this time linked to the medulla oblongata) may be behind people with a natural tendency to sneeze after eating, when they see something pleasant, or even during orgasm. It is already a bad idea, although used well (and even Aristotle would agree with this) it can be seen as a “wonderful” way to improve communication in the bedroom.

the strange medieval epidemic that paralyzed Europe for two centuries

by

At some point in the late 14th century, Charles VI of France stopped moving. Not because of paralysis or fear of his enemies, but because he was convinced that his body was made of glass, and that any touch could shatter it. It was not an isolated case. Those affected by this collective delusion believed that all or part of their body was made of glass. The phenomenon has its own name in the history of psychiatry: the crystal delirium. And his story says disturbing things about how the sick mind always speaks the language of its time. Charles VI, nicknamed El Loco for whatever he may be Charles VI inherited the French throne in 1380, aged eleven. When he turned twenty, he removed his corrupt uncles from power and restored stability to the kingdom’s finances. The people called him le Bien-Aiméthe Beloved. Twelve years later, his definitive nickname would be different: le Fou, the Fool. In August 1392, during a military campaign towards Brittany, the king (23 years old at the time) was riding through the forest of Le Mans when a page dropped a spear. The metallic roar was enough to trigger a violent crisis: Carlos attacked his own knights and killed four before being subdued. It was the first of dozens of episodes that would accompany him until his death in 1422. Pope Pius II wrote that there were times when Carlos believed he was made of glassand that was why he tried to protect himself in multiple ways to avoid breaking, going so far as to have iron rods sewn into his clothes. Something else happened shortly after the onset of the crystalline delirium. In January 1393, the king and several nobles attended a party disguised as “wild men,” wearing linen suits covered in pitch and branches. An errant spark ignited a costume and the fire spread among the men. Only the king and another companion escaped alive, in an event that inspired Edgar Allan Poe to write his macabre story ‘Hop-Frog’. The event went down in history as the Bal des Ardentsthe Dance of the Burning Men. Whether or not that trauma accelerated his mental deterioration is something that historians still debate. When his crises took hold of him, Carlos became a different man: He could sit still for hours and, if he moved, he did so with extreme caution. This had a tremendous political cost: the monarch instability It weakened the French court and allowed rival factions to vie for power, exacerbating the challenges France faced in the midst of the Hundred Years’ War with England. In 1415 his troops were crushed at Agincourt, and in 1420 he signed the Treaty of Troyes, by which he disinherited his own son. The crystal generation Charles VI was, according to historian Gill Speak probably the first documented case of someone believing their entire body was made of glass. But he was far from the only one. The first medical text that records delirium as a recognizable condition dates from 1561, work of the Dutch doctor Levinus Lemnius. The phenomenon belonged to a broader category called “scholar’s melancholy”, an ailment that mainly affected men of letters and nobles from the 15th to 17th centuries. The documented cases are as extravagant as they are revealing. A man was convinced that his buttocks were made of glass and that sitting down would make them burst, so he avoided leaving the house in case a glazier tried to melt it to turn it into a window. Another traveled to Murano, the Italian island famous for its glass, with the intention of throwing himself into a furnace and being transformed into a glass. Engraving of ‘The Stained Glass Licensed’ A third nobleman (always unemployed people, the core issue of the topic) believed he was a glass vessel and spent the day lying on a bed of straw. His doctor ordered the bed to be set on fire with the door closed: when the nobleman pounded on the door asking for help, the doctor asked why it had not shattered with so much fuss. The cure was brutal but, apparently, effective. Transparent glass was not, in the 15th century, an everyday occurrence. It was in that century when the Venetian glassmaker Angelo Barovier invented the cristalloa clear, colorless glass that was extraordinarily rare and was seen by many as something almost magical. Before this innovation, neuroses were different: men who believed they were made of clay and later, in the 19th century, people who believed they were made of cement. The content of delusions reflects the culture of each moment: glass was a new material and therefore became the object of delusions. Glass, specifically, offered transparency: being made of glass meant being precious and fragile, a form of grandeur and isolation at the same time. Miguel de Cervantes published ‘El licensed Vidriera’, one of his ‘Exemplary Novels’, in 1613. The protagonist, Tomás Rodaja, is a brilliant and poor student who, after ingesting a love potion, is convinced that his body is made of glass due to the delicacy and subtlety of the material, with an admirable and delirious internal logic. It is a clear sign that delirium has its corresponding literature at the time: Robert Burton cataloged the phenomenon in ‘Anatomy of Melancholy’ (1621) as a symptom of melancholy, and Descartes, in his ‘Meditations on First Philosophy’ (1641), used the “glass man” as an example of madness to distinguish his own philosophical doubts from the delusions of a sick brain.

Humanity has been wondering for years how to adapt to climate change. The Mayans already achieved it centuries ago

by

Beyond its architecture, urban planning and art, there is an aspect of the Mayan civilization that fascinates archaeologists: its decline. Over time, historians have understood that the decline was not sudden nor did it respond to a single factor, rather there was a sum that included changes in trade routes, wars and, above all, adverse weather, with droughts. severe and prolonged. Now we know something more. Even during the stages of Classic Terminal (800-1000 AD) and Postclassic (1000-1500 AD), while large urban centers succumbed, there were settlements that adapted to climate changes. What has happened? Which a group of archaeologists has just published an article in which they capture their years of research in a Mayan settlement located in ‘Birds of Paradise’, some wetlands located in the north of Belize. The site itself is not new. Scientists identified it long ago a few years with the help of lidara tool that is revolutionizing archaeology. What is new are the conclusions that its analysis has left. He study is published in the magazine PNAS (Proceedings of the National Academy of Science) and, among other issues, concludes that the wetland offers valuable information about how the Mayans responded to the social and environmental changes they dealt with during two crucial stages of their history: the Classic Terminal and Postclassic, a period that goes from the 9th to the 16th centuries. What have they found out? As they explain from New York University (NYU), to which the main author of the study belongs, one of the most interesting readings that the site leaves is the extent to which the Mayans adapted to the vagaries of the climate. Basically, researchers have proven that at a time when large urban centers were abandoned, pressured in part by intense droughtsthere were Mayan settlements that managed to survive in the wetlands. As? For its ability to adapt to the environment. And how did they do it? Taking advantage of the means they had at hand. “Wetlands provided resources for hunting and fishing to ancient populations, in addition to serving as refuge in periods of drought and social upheavals,” they explain from NYU. The environment supplied them with something else, equally or even more valuable for their settlements: construction materials. The site in question that they have analyzed in Belize in fact includes eight mounds of earth that could have served as a base for building buildings and a large elevated limestone platform. The experts also rescued wooden posts, animal remains and ceramic artifacts, clues that tell us about how life continued while other nearby urban centers declined. What do the experts say? “Together these findings reveal a highly adaptable community with diverse tools, food and construction materials. It shows us that Mayan communities could change habitats and survive extreme climates,” explains Timothy Beachprofessor at the University of Texas at Austin, who nevertheless recognizes that “we still do not know the size of this wetland population and its functioning.” Now archaeologists aim to go one step further. “Our next moves include expanding the excavations to understand how the Mayans built with unconventional wood, how they ate, and how this settlement fit into a region that was suffering from widespread abandonment.” Why is it important? Because of the historical era we are talking about. In their article, the researchers assure that the Belize site demonstrates the ability of the ancient Mayans to adapt to “the profound challenges” that they had to live through from the 9th century AD. For reference, a team led by the University of Cambridge discovered not long ago that between 871 and 1021 they happened eight persistent droughtsof at least three years, in the Yucatán Peninsula. The worst of all actually lasted more than a decade. The scientists arrived at that conclusion after analyzing a stalagmite from a Yucatan cave. And, beyond how spectacular it may be, the data is interesting because it tells us about the challenges that the Mayans faced during the Terminal Classic (800-1000 AD), when the limestone cities of the south they were abandonedthe dynasties declined and civilization moved north, losing part of its political and economic power in the area. Are there more conclusions? “As the large urban centers of the Mayan regions succumbed to interconnected socio-environmental factors, the communities of the Birds of Paradise complex persisted through that transition by constructing a series of elevated structures of earth, stone and wood with direct access to the abundant resources and connectivity offered by the riparian wetland system,” reads the article published in PNAS. “It provides evidence for persistent populations between the Elevated Interior Region and coastal regions during the Terminal Classic to Postclassic. While nearby highland urban centers were abandoned, this population continued to emphasize wetland agriculture and provides our best evidence for other subsistence strategies, such as fishing and gathering other proteins, reflected in the faunal assemblage,” they add the researchers. What did they dig? That is another of the surprises that the study leaves behind. Archaeologists discovered what NYU describes as “the largest collection of architectural wood” located inland, as well as artifacts that help historians understand everyday life in the wetlands. It may seem like a minor issue, but it is not common to find remains of wood in Mayan sites. On the contrary. Their very nature causes them to degrade in tropical environments. In Belize, experts have discovered “a unique opportunity” which allows them to better understand how the ancient Mayans built, what types of wood they used and how they used each one. Is it so uncommon? The majority of preserved Mayan wooden remains are figurines, spears and boxes that were recovered mainly in caves in Belize at the beginning of the 20th century. Remains have also been found in mountainous and saline areas in the south of the country. The new findings go further. “It challenges long-held beliefs that sites like this could not survive in the American tropics and suggests we might be overlooking similar sites,” admits Lara Sánchez-Morales, professor of anthropology … Read more
