Greek shipwrecks open to public as underwater museums

For decades the prospect of looters and even well-meaning recreational divers damaging Greece’s vast underwater cultural patrimony made SCUBA diving illegal in Greek waters. Since 2005 diving has been allowed but only in very restricted circumstances, mainly to archaeological teams excavating ancient shipwreck sites. A new initiative under the BLUEMED program will now open ancient shipwrecks to the public who will be able to explore the sites via guided diving.

The first site to open is a 5th century B.C. wreck found near the uninhabited island of Peristera opposite the island of Alonissos. When the Peristera wreck was discovered and excavated in the early 1990s, it upended the historical understanding of ancient Greek shipping. Before this discovery, historians thought the largest merchant ships in Greece were built by the Romans in the 1st century B.C. and were no more than 70 tons carrying 1,500 amphorae. The Peristera ship was huge at 126 tons, the largest ship of the Classical era ever found in the Aegean, and it carried a cargo of more than 4,000 amphorae (that we know of; there was almost certainly other cargo on board that has not been found).

Thousands of ancient vases, the vast majority intact, lie in layers. Fish, sponges and other sea creatures have made the amphoras their home, adding color and life to the site. In some places, the cargo towers above divers as they pass along the perimeter of the wreck.

“It is very impressive. Even I, who have been working for years in underwater archaeology, the first time I dived on this wreck I was truly impressed,” said Dimitris Kourkoumelis, the lead archaeologist on the project preparing the site for visitors. “It’s different to see amphoras … individually in a museum and different to see them in such concentration.”

While any exposed wood of the ship itself has rotted away, the great mounds of amphorae surviving in situ make for an incredibly dramatic vista in a setting of great natural beauty within the National Marine Park of the Northern Sporades. Three other shipwrecks in the West Pagasitikos area have been selected as pilot sites for the tour program by Greece’s Ministry of Culture and Sports.

To prepare these locations for diving tours, Ephorate of Antiquities experts inspected the shipwrecks, cleaning them of trash and any modern interventions, documenting their current condition and status in exhaustive detail and designating “microregions” of the underwater archaeological monuments to serve as diving tour routes. The wrecks and topology of the seabed were surveyed with 3D scans and high-resolution photogrammetry performed by autonomous submarine vehicles. The ecology of the sites were also mapped and documented with a particular focus on the biodiversity of the marine environment.

The first of the guided tours took place last weekend with small groups of divers. The boat departed from the harbor of Steni Valla on Alonissos for the short trip to the Peristera wreck. During the jaunt on the boat, tour guides gave the visitors a rundown of the historical context of the shipwreck they were about to explore. Informational panels positioned along the perimeter of the site itself provided more explanation of what they were seeing.

“It was an amazing opportunity … to dive at last on an ancient wreck,” said Kostas Menemenoglou, a 39-year-old recreational diver from the central town of Volos. “It was a fantastic experience. It’s really like diving into history.”

Revolutionary War hero may have been intersex

A recent investigation into the remains of Revolutionary War hero and Father of the American Cavalry Casimir Pulaski strongly indicates that he was female or intersex.

Born to a noble family is Mazovia, Poland, in 1748, by the time he was in his early 20s, he was a fierce fighter, a Polish patriot in the struggle against Russian expansionism. His military skills and courage were widely recognized in Europe as Poland hurtled towards the First Partition in 1772. When his small army of patriots were defeated and Poland was dismembered by Russia, Austria and Prussia, Pulaski was forced into exile for attempting to assassinate Russia’s puppet king of Poland Stanislaw II Augustus, eventually making his way to America where he took on the cause of Independence with great fervor.

Recommended to George Washington by Benjamin Franklin, Pulaski proved himself in the field at the Battle of Brandywine on September 11, 1777, forestalling the British advance and very likely saving George Washington’s life by giving him the chance to escape. Two days later he created Brigadier General of the Cavalry. Within six months he requested and was authorized to raise an independent cavalry corps. It was a successful combat unit, characterized by Pulaski’s hit hard and run tactics. He was shot and fatally wounded at the Battle of Savannah on October 9th, 1779. He died two days later.

King Stanislaw said when he heard the news “Pulaski has died as he lived, a hero, but an enemy of Kings.” A statement he probably meant as a burn but Pulaski would absolutely have taken as a compliment, especially from a weak faux monarch like that.

Several stories whirled around about what happened to his remains. One of the more widely circulated stories was that he’d been loaded onto a cargo ship, the Wasp, bound for Charleston but when he died, the crew threw him overboard because the stench of his gangrene was so oppressive. It’s not the most likely fate for a cavalry brigadier general, especially since the sea voyage from Savannah to Charleston was so short so really there was no urgent need to dump him overboard like a sack of rotten potatoes. God knows what kinds of smells those sailors were used to. Another story was that he’d been buried at a plantation in Greenwich, just outside of Savannah.

After decades of discussion and funding struggles, the city of Savannah erected a monument to the noble cavalryman. The Pulaski Monument was inaugurated in a ceremony on January 8th, 1855. Colonel William P. Bowen, grandson of the owners of the plantation where family lore said Pulaski had been buried, summarized the evidence that the monument would also be the burial place of Pulaski’s remains. According to Bowen’s aunt, a 14-year-old girl at the time of Pulaski’s death, and the plantation’s groundskeeper, Pulaski’s body was transported to his grandparents’ estate in Greenwich and buried next to a palmetto tree and a glossy holly bush. When the monument was built, Bowen had the spot excavated and there was indeed a body buried there. The bones were closed in a metal box which was placed inside the monument.

In the 1990s, the monument’s structure was failing and had to be dismantled and reconstructed. When the monument was opened, they found a metal container, heavily corroded by rainwater. It was filled with neatly stacked bones, skull on top. The bones were examined in the State crime lab by forensic specialist Karen Burns. She found that the pelvis was female with the characteristic oval shape. So it seemed these were not the bones of Cazimir Pulaski after all.

Or were they? Burns considered the possibility that Pulaski may have had congenital adrenal hyperplasia, ie, was genetically female with ovaries and uterus but due to high testosterone levels had masculine external sex characteristics. Portraits indicated he had a receding hairline and thin moustache. He was of slight build, a few inches above five feet tall, had never married nor had any children. He was something of a lone wolf, both in his private life and as a military leader. He didn’t womanize, didn’t drink, didn’t fraternize with his comrades. A non-standard body type could have been a factor in this aspect of his personality. It’s not out of the realm of the possible that the Father of the Cavalry might have been intersex without him or anyone else realizing it.

Baptismal record indicates he was baptized at home due to what is described as a debilitatus. The baby was otherwise healthy and there is no evidence that Cazimir suffered any illness in his youth. The reference to a “debility” and the private baptism could reasonably have been a reaction to atypical sex characteristics. Whatever the circumstances attending his baptism, he was raised as a boy, was trained in cavalry combat as any young nobleman of his time was and excelled at it, besting both of his brothers.

A 10-year investigation of the bones, including an attempted comparison of mitochondrial DNA in the bones from the Pulaski Monument and bone fragments recovered from the grave of Pulaski’s grandniece Teresa Witkowska. The original investigation was unable to retrievable viable samples of mitochondrial DNA from those fragments.

Most of the remains were reburied in 2005 in a crypt next to the restored monument, but castsof the original bones and a few of the real ones were kept for future study. The investigation picked up steam again recently.

New tests on the same bones sampled the first time did retrieve mtDNA, but the comparison between a tooth from the Pulaski Monument bones and a femur from the Witkowska remains did not return a match. Those samples had been cut into, however, making them susceptible to contamination, so the team tried again with two different bone samples from the monument (a tallus bone) and Pulaski’s grandniece (a metatarsal). The mtDNA connection excludes 99% of the population, so that means the bones are either Cazimir Pulaski’s or there was some other random Pulaski relative buried in Savannah at the same time, which is so extremely unlikely it can be dismissed.

“One of the ways that male and female skeletons are different is the pelvis,” Virginia Hutton Estabrook, an assistant professor of anthropology at Georgia Southern University, told NBC News. “In females, the pelvic cavity has a more oval shape. It’s less heart-shaped than in the male pelvis. Pulaski’s looked very female.”

While the Pulaski skeleton showed tell-tale signs of extensive horseback riding and a battle wound on the right hand that the general is known to have suffered, the facial structure and jaw angle were decidedly female, Estabrook said.[…]

Was Pulaski aware of being different from the men around him?

“Probably he was not completely aware,” Estabrook said. “What we do know about Pulaski is that there were enough androgens (male hormones) happening in the body, so that he had facial hair and male pattern baldness. Obviously, there was some genital development because we have his baptismal records and he was baptized as a son.” […]

Told of the revelations about Pulaski, Richard Zawisny, president of the annual Pulaski Day parade, admitted, “I’d heard something about this before, but I’m a little shocked by this.”

“But in this day and age, I don’t think it will matter to most people,” he said. “I really believe that the majority won’t care, and it doesn’t take away from the fact that Pulaski was a Polish-American hero.”

The study of Casimir Pulaski’s skeletal remains is the subject of an episode of America’s Hidden Stories that premiered on the Smithsonian Channel Monday, April 8th, at 8:00 PM. It’s fascinating.

There’s only so much “Wow!” “Amazing!” I can take

I’m watching the Egypt Live broadcast but I have to get up and do something else every ten minutes because the breathless exclamations are just too much for me to stand. STOP SAYING WOW, JOSH. And especially stop talking over people who have something substantive to say just to exclaim “Wow! Amazing!”

8:30 lol did Zahi Hawass just call him fat? Okay, I’m getting into this now.

Note: Hawass is just shy of his 72nd birthday. Look at him haul himself through these tight passages without breaking a sweat.

Hmm… Split screen with ads on the right and the live action on the left. I don’t hate it. In fact, if you’re going to do breakouts to pre-recorded explanatory bits, then keep the live thumbnail going with that too.

Ugh. Jokey food segment. The goat in the beginning was bad enough. The falafel punsterism is so much worse.

Oh hey, I didn’t know canopic jars were named after a type site! Beautiful examples in this tomb.

Zahi, no. Please. Not the curse.

I find Waziri’s calm descriptions and handling of the artifacts rather a relief after the extraness of Hawass and Gates.

I’ll tell you what, this gives you a good idea of what a hard job it really is to excavate sites like this. I’m not claustrophobic at all, and I can’t help but feel uneasy at the tight spaces and oppressively close rock walls deep underground.

“The adventure in archaeology makes me completely forget the pain. [moans in pain]” — Zahi Hawass

And we have reached the big limestone sarcophagus that will be opened live. They didn’t announce in the press materials that they’d open two less important ones before they even got to this one.

Mahmoud is the unsung hero of this broadcast.

I’m going to have to find out more about the wax heads and their revival in the New Kingdom.

That is the most perfectly wrapped mummy I’ve ever seen. I’ll say it: Wow. Amazing.

Egyptian sarcophagus to be opened on live TV

An ancient Egyptian sarcophagus will be opened live in a two-hour television special to air simultaneously at 8:00 PM Sunday on the Discovery, Travel and Science channels. Expedition Unkown: Egypt Live will be hosted by one Josh Gates who is described as an “explorer,” and who in his capacity as a certified SCUBA diver assisted in an archaeological excavation once in the 1990s. Other than that, it seems his bailiwick is hosting TV shows and traveling places. The actual opening of the sarcophagus will be done by archaeologists under the ever-watchful (and promotion-keen) eyes of Egyptologist Dr. Zahi Hawass and Mostafa Waziri, the secretary-general of the Supreme Council of Antiquities of Egypt.

The limestone sarcophagus was found in the necropolis of Tuna el-Gebel in Minya province, about 210 miles south of Cairo. More than 50 Ptolemaic era mummies were found there earlier this year. The sarcophagus is likely older than that, however, as it was discovered in deeper chamber.

Viewers will have the rare opportunity to see the inner chambers of an excavation site, where archeologists recently uncovered a network of vertical shafts leading to an underground network of tunnels and tombs with 40 mummies believed to be part of the noble elite.

The massive underground complex of chambers is a treasure trove of antiquities – all laying undisturbed for thousands of years. But there are several chambers yet to be explored – and many more discoveries to be revealed, including a mysterious limestone sarcophagus found buried deep within the complex. The identity of the mummy inside has been a mystery for 3,000 years… Possibly until now.

Or even more likely there will be no identifying inscriptions. For that matter, there may not be any mummified remains to speak of remaining inside. There’s a very strong possibility of an Al Capone’s vault situation here, but the live broadcast works as a marketing tool either way since viewers will get two hours worth of the “come see the ancient wonders of mysterious Egypt” pitch.

This is the first time an Egyptian sarcophagus will be opened on live TV, but it’s only the technology that’s been updated. Making a spectacle of the dead of ancient Egypt is part of a long tradition of mummy voyeurism and exploitation going back centuries. Dr. Augustus Granville garbed it in a loincloth of science when he performed an autopsy of the mummy of Irtyersenu before a large crowd in 1825, the surgical theater lit by candles made from what he thought was beeswax he scraped off her mummy but turned out to be Irtyersenu’s own body fat in the form of adipocere. Dr. Thomas Pettigrew became known as “Mummy” Pettigrew for the hugely popular mummy unravelling parties he threw for Victorian Britain’s moneyed elite.

Soil, not advanced technology, preserved Terracotta Army’s weapons

Since the fearsome 2,000-strong terracotta army of Emperor Qin Shihuang (259–210 B.C.) was first excavated in the 1970s, the bronze weaponry has stood out for its remarkably good state of preservation. Tens of thousands of arrowheads, spear tips, lances, swords, hooks, crossbow triggers and other bronze parts of complex weapons have survived even as their wooden components decayed to nothingness. Many are still shiny, sharp and show no sign of corrosion whatsoever. Traces of chromium found on the bronze parts have led scholars to hypothesize that the unusually excellent condition was attributable to an early form of chrome plating used as an anti-oxidation measure, a technology only otherwise known to have been invented in the 20th century.

A new study published in Scientific Reports suggests that the chromium residue found on the blades was an element in the lacquer applied to the wood or bamboo parts of the weapons — grips, spear handles, lance and arrow shafts, crossbows, etc. — not to the bronze edged parts. In the decay of the organic material, the chromium residue contaminated the blades.

In the absence of an anachronistically advanced rust-prevention technology, what then has kept blades and points in such pristine condition? The study authors think the answer is in the composition of the bronze and in the soil itself. Bronzes with higher tin content are prone to develop rich-tin layers on the surface that prevent corrosion. Testing of the surface of batches of bronze arrows from the Terracotta Army archers found the ones with the higher tin content were more stable. The presence of arsenic in the bronze also helped prevent corrosion.

The alkali nature of the soil is another highly significant factor that this study is the first to explore.

The Terracotta Army is located in the southern edge of the Chinese Loess Plateau, a 640,000 km2 area covered by silt-sized aeolian sediments that make the bulk of the soil. Large-scale models predict pH values around 8–9 for the Lintong area43, and this was confirmed by our on-site measurements of soil samples from Pits 1 and 2, showing pH values between 8.1 and 8.5 (Table S3). Burial soil pH is a paramount parameter predicting metal preservation, as it is correlated with redox potential, drainage conditions, biological activity and aeration. Additional characteristics of loess of potential relevance here are its low organic content and predominantly very small particle size. We propose that the moderate basicity and low organic content of the loess would have prevented the formation of acids that would attack metal integrity. In addition, the very small particle size of the soil would have obstructed the aeration and humidity necessary for metal corrosion. Our proposal is consistent with studies in conservation science which have addressed the optimum conditions for metal preservation in burial environments, noting pH levels of 8–8.5 and small particle size as optimum.

The research team tested the claim by placing bronze tokens in an environmental chamber that created accelerated aging conditions and by burying bronze in soil excavated from Pit 1 of the tomb. The tokens and the buried bronze both remained in pristine condition. A bronze token buried in organic-rich, slightly acidic soil with a pH of 5.9 as a control, on the other hand, quickly showed signs of corrosion.

In conclusion, the perplexing suggestion that Qin weapon makers used an arcane chromium-based technology to prevent weapon rust has been refuted. Efforts should be made to update museum displays and other popular literature about the site with this new information. Furthermore, we predict that chromium will be detected on the surface of metal objects from other sites where they may have been in association with chromium-bearing lacquered parts, i.e. more likely on weapons than on ritual bronzes. The use of chromium-rich compounds in the manufacture of ancient lacquer should be in the agenda for future research, together with further technological study of the sharp and lustrous blades.
