Photo by North News.In 2013, an excavation in advance of future construction at the site of the Neptune Shipyard in Newcastle upon Tyne unearthed a unique survivor of Newcastle’s early industrial history: an 80-foot stretch of a wooden railway dating to the 18th century. This railway wasn’t used by trains as they hadn’t been invented yet. It transported wooden “waggons” (chaldrons) pulled by horses. Supported by the sturdy tracks which ran at a slight incline to take advantage of gravity, the waggons were able to carry far heavier loads of coal far more quickly from local collieries straight to the docks of the river Tyne. It was identified as a section of the Willington Waggonway built in 1785.

There are rough-hewn sleepers that are basically intact tree limbs, cut and planed pine sleepers and repurposed ship planks.

It’s the most intact segment of wooden railway ever discovered and, thanks to the waterlogged riverside environment, the best preserved. Those elements alone would suffice to make it a find of international significance, but the Willington Waggonway has another remarkable feature: it’s the earliest Detail of wash hole section, lined with stone pavers.

It’s also the only railway ever found with a surviving “wash hole,” a stone basin in the track where wagon wheels were cleaned and soaked in water to prevent shrinkage and cracking from friction and heat. Wash holes were known from historical records, but this is the first one to be discovered.

As soon as the timbers were exposed to the air, they began to decay. Organic materials that have been preserved for centuries in waterlogged soil need immediate conservation once they’re excavated to keep them from drying out, rotting and/or being devoured by an assortment of critters. You can’t leave them in situ unless you rebury them for their own protection, and because the site was going to be redeveloped, the reburied waggonway could easily have been damaged, even destroyed, by construction.

The National Railway Museum stepped into the breach and collected the remaining timbers. They are being conserved together with their TWAM brethren at the conservation laboratories of the York Archaeological Trust which has extensive expertise in and specialized equipment for the preservation of ancient wood.

Photo by Beamish Transport Online.Trust experts analyzed samples from the wood to determine their individual conditions and preservation needs. The diagnosis was that the timbers needed long-term soaking in a Polyethylene Glycol (PEG) bath followed by freeze-drying. The PEG replaces the water molecules in the wood with a waxy material that maintains the structure without contracting and expanding the way water does. Once the PEG has taken hold, a bout in the freeze-dryer finishes the job of sucking out the last drops of moisture, making the wood stable for display. The whole process can take up to 36 months.

Ian Panter, Head of Conservation, York Archaeological Trust said: “The conservation of the waggonway timbers has been a challenge, not because the wood was very decayed, but the opposite. Many of the timbers were very well preserved but with with pockets of more decay.

“This type of wood always represents a challenge but one which we relished getting to grips with. It is good to see something dating to the early stages of the industrial revolution being conserved, and this makes a refreshing change from the very ancient timbers that we’re usually involved with.

“Having personally been involved with the Lambton trackway, of similar date which was reburied, it is a step forward that something as important as the waggonway is being preserved for future generations.”

Eighty-seven of the timbers have been conserved already. They are now at the Regional Museum Store at Beamish where they are being studied for what they can tell us about 18th century railway construction and maybe even shipbuilding. A few of the preserved timbers, timbers awaiting conservation and stones from the wash hole went on display Friday at the Stephenson Railway Museum as part of the national Festival of Archaeology.

Not all of the timbers are out of danger yet. Fifty of them remain untreated and are at risk of decay unless another £10,000 can be secured to fund their conservation. A campaign with a target of 5,000 has been launched. You can donate to it here. Once the Willington Waggonway remains have been conserved and researched, the plan is to reconstruct as much of it as possible (mostly the intact 20-foot section) for permanent display at the Stephenson Railway Museum.

New imaging approach reveals hidden text from two eras

In the Middle Ages, old manuscripts were recycled for their valuable vellum and parchment pages. The writing was washed or scrubbed off and the leaves filling with new content. Because so many ancient works have been lost, scholars have for centuries attempted to recover the original texts from these medieval palimpsests, often using caustic materials that damaged the pages in the long term. Nowadays researchers have much better options thanks largely to a panoply of imaging technologies that have been a godsend to the study of palimpsests, revealing erased and overwritten text that cannot be seen with the naked eye. Synchrotron imaging is better than Superman because it can see through lead boxes.

Some of the recycled parchments pose greater challenges than others. With the introduction of the printing press to Europe in the 15th century, the demand for bookmaking materials soared. Not only were medieval manuscripts cannibalized for their pages, but the bindings were reused to bind newly printed books. This was a common practice well into the 18th century, so there are a lot of old printed books out there with fragments of medieval and ancient texts hidden in the binding. Scholars knew there might be literary treasures in there, but were stumped by the difficulty of accessing and reading binding materials.

Now researchers at Northwestern University have made a breakthrough. It was a book from the university library’s collection that inspired the new approach. It’s an edition of the Works and Days by the Greek poet Hesiod that was printed in Venice in 1537. Northwestern acquired it in 1870 and out of the 30 known surviving copies of the edition, this is the only one that still has its original slotted parchment binding, a widely used technique in Venice from 1490 to 1670 in which slots were cut into the binding parchment to match the shape of the book spine.

Slotted parchment bindings often used recycled parchments. The ink was usually removed for aesthetic purposes, to make the outside surface of the parchment a uniform color. In this particular book, the ink on the interior parchment surface was not removed. Iron gall ink is acidic and over time, speeds up the oxidation and decay of the parchment.

The Northwestern librarians noticed the slotted parchment binding in the Hesiod and realized its significance. They also saw the faintest hint of text on the book board. Researchers from the Northwestern University-Art Institute of Chicago Center for Scientific Studies (NU-ACCESS) examined the binding in greater detail and found evidence that the writing on the book board had been removed, likely by the bookbinder, by washing or scraping. His efforts weren’t entirely effective, much to our advantage. Over time the gall ink that wasn’t removed had degraded the parchment and the writing began to re-emerge. NU-ACCESS researchers found two columns of text plus marginalia were very dimly visible through the parchment on the front and back covers of the book.

The writing wasn’t legible with the naked eye, so scientists Marc Walton and Emeline Pouyet turned to imaging, starting with visible light hyperspectral imaging. The writing became a little clearer, but it still couldn’t be read. X-ray fluorescence imaging gave the team new information about the chemical composition of the ink, but again, it wasn’t able to bring the ancient text out of hiding. They were going to need a bigger boat, to paraphrase Jaws, and the Cornell High Energy Synchrotron Source (CHESS) was that boat.

[T]he bright x-ray source and fast detection system allowed for a full imaging of the main text and marginalia comments in the entire bookbinding. When the researchers sent the more clearly imaged writing to [Northwestern history and religion professor Richard] Kieckhefer, he immediately recognized it as sixth-century Roman Law code [the Institutes Justinian], with interpretive notes referring to the Canon Law written in the margins.

Walton and Pouyet hypothesize that the parchment originally might have been used in a university setting where Roman Law was studied as a basis for understanding Canon Law, which was a common practice in the Middle Ages. The legal writing was then possibly covered and recycled because it was outdated as society had already struck down the Roman laws to implement church code.

It was an exciting find, but the NU-ACCESS team had greater ambitions. Synchrotrons aren’t exactly a dime a dozen, and most researchers don’t have access to the powerful (and expensive) equipment. Even if they do, rare old books in delicate condition can’t always be shipped to a synchrotron facility. For conservation reasons, they often can’t be shipped anywhere at all. Walton and Pouyet turned to Northwestern’s computer scientists to seek a cheaper, more readily available technology that would be able to read challenging palimpsest texts trapped in bookbindings.

“There is a vast number of wavelengths in the electromagnetic spectrum, and each wavelength has its advantages and disadvantages,” said [Aggelos] Katsaggelos, the Joseph Cummings Professor of Electrical Engineering and Computer Science. “Some of them can penetrate deeper into the specimen, some of them have better resolution, and so on.”

Using a machine-learning algorithm developed by his team, Katsaggelos discovered that not one imaging technique but a fusion of two would yield the best results. His team combined visible hyperspectral imaging, which includes wavelengths within the visible light spectrum to provide high spatial resolution, with x-ray fluorescence imaging, which provides high intensity resolution. The algorithm informed the researchers of the relative contribution of each modality to produce the best image.

“By combining the two modalities, we had the advantages of each,” Katsaggelos said. “We were able to read successfully what was inside the cover of the book.”

Katsaggelos’ data fusion image was so clear that it rivaled an image of the main text produced by the powerful x-ray beams at CHESS.

Walton and Pouyet plan to take this show on the road. They want to examine books in museums and other institutions using the combination of hyperspectral imaging and x-ray fluorescence to read hidden texts on pages and bindings.

Quilts made by men at war to go on display

Three years ago, St. Paul’s Cathedral in London restored and displayed a hand-made altar frontal that had been by intricately embroidered by 133 convalescing soldiers during World War I. Sewing was considered a highly effective form of occupational therapy for soldiers because it could be accomplished while seated, improved manual dexterity and mental focus. The notion of occupational therapy was birthed in the crucible of World War I which left so many men physically and psychologically disabled, but it was a new name for an old practice.

Soldiers and sailors have been stitching masterpieces of the sewing crafts for hundreds of years. It was a longstanding tradition that during lulls in fighting, while prisoners of war or over extended hospital visits, they would hand-stitch quilts, wool work seascapes and embroider their own uniforms. Sailors maintained ships’ sails as part of their duties and therefore had basic sewing skills. Soldiers didn’t have the same job requirement, so if they knew how to sew it was either fortuitous or professional; i.e., they had been tailors in civilian life and were often employed as regimental tailors in the military.

Some of the earliest surviving examples were made in the 18th century using the intarsia technique in which fabric pieces are cut in precise shapes and sewn together so that no seams show. These types of quilts are so difficult to produce that it’s likely they were created by professionals. The imagery is often related to the wars being fought and national identity — comrades, the fatherland, traditional folk tales, etc. The quilts produced in wartime by military men of all levels of stitchcraft experience often used uniform pieces, blankets and random snippets of whatever other textiles they could get their hands on to create geometric designs of dazzling intricacy.

The American Folk Art Museum in New York is putting on the first US exhibition of quilts made by fighting men in wartime from uniform fabric. Most of the quilts on view in the War and Pieced exhibition come from the private collection of Australian quilt expert, historian Dr. Annette Gero. Others are on loan from public and private collections. Many of them have never been publically displayed before.

Immigrant tailors, such as Hungarian-born Michael Zumpf, introduced the intarsia technique into Great Britain. Two masterworks, exhibited to great acclaim in London during the late nineteenth century, feature minutely detailed representations of British military and political leaders, and members of the House of Commons. These elaborate pictorial panels were made using popular etchings of those subjects as templates.

Perhaps the best-known quilts that were made by soldiers and regimental tailors are the complex geometrics fashioned from felted military uniforms. Hand-stitched by nineteenth-century British soldiers, sailors, and regimental tailors during periods of conflict in the Crimea, South Africa, and India, some of these mosaic-like quilts contain as many as twenty-five thousand pieces of fabric. They were once called “convalescent quilts,” it was believed they were made as occupational therapy by wounded soldiers recovering in hospitals. Quilts pieced in simple geometric patterns may indeed have been made in such circumstances, but it is now recognized that the most elaborate quilts were most probably stitched by tailors and soldiers to pass the time and stay out of mischief, to give as gifts to loved ones at home, or were made upon a soldier’s return.

“In the context of war, quiltmaking becomes a life-affirming testament to bravery, loyalty, and an act of redemption for darker human impulses enacted under dire circumstances,” says Stacy C. Hollander[, chief curator of the American Folk Art Museum]. “Memory and experience are fragmented and brilliantly reconstructed through tiny bits of cloth. The uniforms, associated with the best and worst of humanity, are thus transformed into testaments of sanity and beauty, even as the highly organized geometry grants the soldier an illusion of control over the predations of war in which he has both participated and witnessed.”

War and Pieced will run at the American Folk Art Museum from September 6th, 2017, through January 7th, 2018. Next year the exhibition will travel to the International Quilt Study Center & Museum at the University of Lincoln-Nebraska where it will run from the May 25th through September 16th, 2018.

But enough of my yakking. This post is all about the cornucopia of quiltly goodness and there’s so much more bounty to enjoy I had to put it after the jump to keep load times from going insane.

Mummy in Buddha statue goes to court

Two years ago, a 1,000-year-old statue of the Buddha made headlines when a striking CT scan exposed the mummified monk within. The statue was scanned at a hospital in Amsterdam when it was in the country to take part in the Mummies exhibition at the Drents Museum in Assen, the Netherlands. The exhibition proffered the Buddha statue as an example of the extreme practice of self-mummification, in which Buddhist monks spent years starving and poisoning themselves before having themselves walled into a constricted space to die. If three years later their bodies were found mummified, they were considered to have attained the rank of Buddha and their remains were venerated.

According to the information on the exhibition’s website and labels, the monk sealed in the statue was believed to be Master Liuquan of the Chinese Meditation School, aka Zen Buddhism, who died around 1100 A.D. There was no evidence offered in support of this surprisingly specific identification, nor were there any details about who owned the statue. The press materials alluded to this being the first time the statue was allowed to leave China and that it was the only Chinese Buddhist mummy made available for scientific study in the West.

Well, that may all be a big bunch of lies, or at least misinformation of the “Swiss private collection” variety to act as a smokescreen for some very shady dealings in stolen cultural heritage. A lawsuit currently in the Dutch courts presents an entirely different ownership history and identification of the statue and mummy. The plaintiff is the tea-farming mountain village of Yangchun in southeastern Chinese province of Fujian which claims the statue was stolen from a temple there in 1995. The defendant is a Dutch collector, who bought the statue and the human remains it contains in Hong Kong in 1996.

In March of 2015, one of the villagers saw a photograph of the statue on display at the Mummy World exhibition at Budapest’s Natural History Museum. He immediately recognized it as the Zhanggong Patriarch, a statue containing a mummified monk that he and his fellow villagers have venerated for centuries.

The lawyers will argue that according to Dutch law “a person is not allowed to have a known body in their possession,” Holthuis said.

“We also have enough evidence to prove that the statue is indeed the one that was stolen from the temple,” he added.

“The fact that it was sold a few months after it was stolen, that it contains certain texts referring to the name ‘Zhanggong’ and that its dating more or less corresponds to the period that the monk was alive,” were some of the arguments which will be presented, he said.

There are some pictures of it in the temple in 1989, and the village still has the clothes and crown the statue was wearing before the thieves stripped it. The picture alone isn’t as dispositive as you might think because of those clothes and crown. They obscure some of the identifying detail of the statue which has been displayed without its traditional accessories in the mummies exhibitions.

According to centuries of village tradition, the statue contains the remains of a monk named Zhang who moved to the village with his mother when he was a boy during the Song dynasty (960–1279). He went from cowherd to Buddhist monk to a gilded mummy worshipped by generations of residents. (There is no suggestion of self-mummification. He was mummified after his death as an indication of the great esteem in which he was held, an account that is consistent with the discovery that his organs had been removed and replaced with paper fill.) The villagers prayed to him at all major festivals and seasonal events. Each year the statue was transported through the village stopping at every house, and the monk’s birthday was celebrated every year with a grand festival. The village’s ancestral records seemingly confirm the oral history; they document the presence of the Patriarch as early as the Song Dynasty.

Villagers in Yangchun, China, pray in front of gray replica of the stolen statue. Photo by Gilles Sabrie for The New York Times.The theft of the Zhanggong Patriarch was devastating to the villagers. Some of the older residents had risked their lives to protect him from the iconoclastic marauders of the Cultural Revolution. The statue was kept constantly on the move for its safety, hidden in pits and people’s homes, sometimes moved twice in a night. They put a replica in his place, a rather rough grey version of the elegant gilded original, and the villagers still pray to it.

There’s one big problem. Nobody knows where the statue is right now. Apparently the collector, Dutch architect Oscar van Overeem, traded it with somebody in 2015 and he’s not saying who. The timing of this swap is curious, especially in the light of van Overeem’s strenuous denial that his mummy was the Zhanggong Patriarch. He insisted that he had easily disproven the village’s claim to the Chinese representative who contacted him to negotiate repatriation, but worked out a deal anyway to donate the statue to an unnamed Buddhist temple near Yangchun. He had struck this bargain, he said in May of 2015, “because he believed it deserved to return to its homeland ‘to be incorporated in truly Buddhist surroundings’ and worshiped ‘by those who love and appreciate him.'”

So in May of 2015, the collector believed that the mummy deserved to be home among those who love and pray to him, but I guess that belief wasn’t all that strongly held because the statue and mummy are not in any Buddhist temple near Yangchun. It’s nowhere to be found. Whoever the third party is has little incentive to come forward, so even if the village wins in court — which would be a landmark decision for Chinese cultural patrimony repatriation because it would be the first time a heritage object is returned due to the courts rather than through diplomatic channels — it could still be left bereft of its beloved Zhanggong Patriarch.

1759 British cannonball, still live, found in Quebec City

Last Friday, July 7th, a construction crew working on a building site at the corner of Hamel and Couillard streets in Old Quebec, the historic center of Quebec City, Canada, unearthed a large cannonball from the French and Indian War. The crew took pictures of themselves with the 200-pound projectile as if it were a movie star. They moved it around, struck poses and generally had a blast with their discovery.

They didn’t realize at the time that the blast they were having could well have been literal. It was archaeologist Serge Rouleau, called in by municipal authorities to examine the find, who saw that the ball still held a charge. His examination determined that the cannonball was of British manufacture and was fired at the old city in the Battle of the Plains of Abraham in 1759, or in the siege preceding it. Rouleau had taken the ball home with it to study — an odd step to take when dealing with explosive devices of any age — so when he realized his bouncing baby bomb still has what it takes to blow him up and burn his house down around the splattered specks of tissue that were once his body, he called in the experts.

A team of army munitions technicians was dispatched from CFB Valcartier to collect the ball and neutralize it.

“With time, humidity got into its interior and reduced its potential for exploding, but there’s still a danger,” said Master Warrant Officer Sylvain Trudel, a senior munitions technician.

Trudel said such balls were meant to set fire to the buildings they penetrated.

“The ball would break and the powder would ignite, setting fire to the building.”

This was a brutal weapon in the mid-18th century, and Quebec City was deluged with them during the Seven Years’ War when Britain fought and shot its way to taking control of much of French North America. The Battle of the Plains of Abraham was the culmination of three months of intensive bombings by British troops besieging the city of Quebec. From the their position at Lévis, just across the St. Lawrence River from Quebec, the British launched a near-constant barrage of deadly artillery fire starting on July 12th, 1759. Over the next three months, they would set the city alight with 40,000 solid iron cannonballs and 8,000 incendiary bombs. On September 13th, the British and French engaged in an infantry battle on a plateau outside the city knows as the plans of Abraham. It lasted less than hour. The British were victorious, chasing the French out of the city and ending the siege. The siege and battle took a massive toll on Quebec and its environs. The city and surrounding countryside were in smoldering ruins when the smoke from the plains of Abraham cleared.

On a global scale, the battle permanently altered Canadian geopolitics, setting the stage for the British conquest of Canada and the French withdrawal. France’s forces in Canada were weakened by the loss and came under increasing pressure from British troops on the continent. It would take another five years for the conflict to come to its final conclusion in the Treaty of Paris (1764), but when the quill pens were finally put to parchment, France had ceded almost all of its American territories, including Canada, to Britain.

Musn't touch the live ammo. Photo courtesy Lafontaine Inc.The 258-year-old live cannonball has now been moved out of the archaeologist’s house to a safe place where the munitions disposal experts will determine if it can be safely neutralized. If not, it will be detonated and destroyed.

“Old munitions like this are hard to predict,” Trudel said. “You never know to what point the chemicals inside have degraded.”

If it is salvageable, the cannonball will find a loving forever home at a local museum.
