Museum acquires rare sufragette banner found in Leeds charity shop

The People’s History Museum (PHM) has acquired a very rare suffragette banner that was made in Manchester in the early 1900s and will now return to its native city again more than 80 years of exile in Leeds. Created by premiere Manchester banner maker Thomas Brown & Sons, the banner celebrates the founding of the Women’s Social and Political Union (WSPU) by Emmeline Pankhurst, one of the fiercest and most committed suffragette leaders, in her home at 62 Nelson Street, Manchester, in 1903. The date of its manufacture is not known, but the banner glows with the colors of the WSPU campaign: green signifying reform, white purity and purple dignity. The green, white and purple weren’t adopted as the WSPU’s official colors until 1908.

The WSPU marched and assembled under their banners, but unlike many of their sisthren in the cause, they took an explicitly militant stance. Sick of failed attempts to extend the franchise by ostensibly allied politicians, the WSPU took as their motto “deeds not words” and hit the streets. They tied themselves to railings, blew up mailboxes, went on hunger strikes when they were arrested and refused to eat even under threat of force-feeding. They made a very effective nuisance of themselves until World War I broke out in 1914 and the WSPU suspended all its activities.

As far as researchers have been able to determine, the banner was taken to Leeds in the 1930s by Edna White. It was sold to the charity shop after her death and this rare textile treasure remained in the shop, unrecognized and unappreciated, for 10 years. The charity shop put the banner up for auction on June 20th of this year where it was bought by a private collector.

The People’s History Museum, which has the largest collection of trade union and political banners in the world and a top notch textile conservation studio to ensure their long-term health, wasted no time. They reached out to the collector and agreed on a buying price for the banner. They then raised most of the money in grants from the Arts Council England/V&A Purchase Grant Fund and the Heritage Lottery Fund. With £5,000 still to go, the museum turned to crowdfunding. The Bring Manchester’s Suffragette Banner Home campaign was an almost instant success, meeting the original target in a week.

The PHM has added another £2,500 as a stretch goal to help fund interpretation of the newly acquired banner for its display in a 2018 exhibition celebrating the centenary of the passage of the Representation of the People Act which granted suffrage to all men 21 and older and women 30 and older. (Women 21 years of age and above were not enfranchised until 1928, a matter of a few weeks after Emmeline Pankhurst’s death.) The rest of the stretch money would go to getting the rest of the museum’s suffrage collections in top shape and creating learning resources and events associated with the exhibition. They’ve only raised a few hundred pounds of the stretch goal with just over two weeks to go.

Helen Antrobus, Programme & Events Officer at PHM, says…

“This is a truly spectacular piece, beautifully crafted and powerfully representative of its time. It is also an important part of the nation’s social history and we hope to find out more about Edna White and her suffragette story as part of this project’s research. The banner’s life began in Manchester and we’d like to continue its life by sharing its story with our visitors who travel across the region, nation and world to join us on a march through time that narrates Britain’s struggle for democracy.”

The campaign will ensure that the banner not only becomes a part of the People’s History Museum collection, but that plans are in place for its continued care and conservation by the museum’s specialist team.

Cuneiform tablet is oldest (& newest) trigonometric table

Mathematicians at the University of New South Wales (UNSW) in Sydney, Australia, in think they’ve cracked a cuneiform code that has given rise to vigorous debate in the mathematical community for almost a century. The bone, or in this case clay tablet, of contention is known as Plimpton 322 and has been in the Columbia University collection since it was bequeathed to them in 1936 by the wealthy publisher and avid collector of historical written materials George Arthur Plimpton. (His grandson was George Plimpton, author, literary critic and one of the shrinks Matt Damon chases away in Good Will Hunting.) George Arthur left the tablet and the rest of his exceptional collection of rare books and manuscripts to the Butler Library; they are now in the university’s Rare Book and Manuscript Library.

The tablet is five inches wide, 3.5 inches high and .8 inch thick and features a table of cuneiform numbers four columns across and 15 rows long. The outer left edge is broken, possibly in the modern era because there are remains of glue indicating a repair attempt with the now-missing piece. This break took some of the first column figures with it, forcing mathematicians to have to extrapolate what the complete numbers were based on the extant ones. Experts think the complete table was six columns wide and 38 rows long. All of the numbers are in Babylonian sexagesimal (base 60) notation.

Its origins are obscure because the tablet was one of hundreds acquired by roving antiquarian/adventurer/novelist/diplomat Edgar James Banks starting in the late 19th century. He sold it to Plimpton in around 1922, reportedly for $10. Neither of them realized the significance of the cuneiform text. Based on the writing style and formatting, researchers believe the tablet was created in the Sumerian city of Larsa in what is today southern Iraq between 1822 and 1762 B.C., right around the time of Hammurabi (c. 1810-1750 B.C.), 6th king of the First Babylonian Dynasty and promulgator of the law code that bears his name. Several other tablets with inscriptions of Babylonian mathematics came from Larsa.

Mathematicians have been studying Plimpton 322 since it was first published at the end of World War II and there have been rollicking debates on the purpose of the table, whether it’s a complex accounting tool, a mathematical table (if so what kind), a teacher’s edition list of answers for math students or something else entirely. Austrian mathematician and historian of science Otto Neugebauer recognized that the numbers on the table are Pythagorean triples, two different integers that squared and added together equal the square of the third integer, but to what end did ancient scholars take the immense trouble to compile the lists?

The UNSW team posits that it is indeed a trigonometric table, but one that takes a previously unknown approach to calculation.

“Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles,” said Dr Daniel Mansfield of the School of Mathematics and Statistics in the UNSW Faculty of Science.

“It is a fascinating mathematical work that demonstrates undoubted genius. The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.

“This means it has great relevance for our modern world. Babylonian mathematics may have been out of fashion for more than 3000 years, but it has possible practical applications in surveying, computer graphics and education. This is a rare example of the ancient world teaching us something new.”

Until now, the Greek mathematician Hipparchus has been granted the title the Father of Trigonometry because he designed a table in a circle that was long credited with being the oldest known trigonometric table. If the scribe who wrote Plimpton 322 had signed his work, Hipparchus would have had to take that crown off his own head and put it on his Sumerian predecessor’s.

“Plimpton 322 predates Hipparchus by more than 1000 years,” says Dr Wildberger.

“It opens up new possibilities not just for modern mathematics research, but also for mathematics education. With Plimpton 322 we see a simpler, more accurate trigonometry that has clear advantages over our own.” […]

“Plimpton 322 was a powerful tool that could have been used for surveying fields or making architectural calculations to build palaces, temples or step pyramids,” added Dr Mansfield.

Their research has been published in the journal Historia Mathematica and can be read in its entirety here (download it now before it ends up behind a paywall).

This may be the nerdiest web of nerdery I’ve ever woven (which is saying something), but when I first saw this story I couldn’t help but imagine the following dialogue.

Plimpton 322: I’m an idiot because I can’t make a lamp?
Diogenes: No, you’re a genius because you can’t make a lamp.
Plimpton 322: What do you know about trigonometry?
Diogenes: I could care less about trigonometry.
Plimpton 322: Well did you know without trigonometry there’d be no ziggurats?
Diogenes: Without lamps, there’d be no honest men.

I’ll see myself out.

Neolithic homes, 19th c. whale skeletons found on Orkney

Archaeologists excavating Cata Sand, a bay on the Orkney island of Sanday, have unearthed the remains of an Early Neolithic house and at least a dozen 19th century whale skeletons. The prehistoric structure dates to between 3400 and 3100 B.C. and is fairly extensive with its original hearth and remains of walls. Northwest of the core structures is a second hearth that archaeologists believe is from a later expansion and reconstruction of the house.

Prof [Colin] Richards said: “The early Neolithic house is both interesting and unusual in having been built on a deep layer of sand, which rests on rounded beach stones.

“At least two construction phases have now been recognised. The primary house has a stone set hearth, internal pits and boxes, and remains of the lower courses of a double-faced thick stone outer wall and small dividing stones, which partition the house into different living areas. This phase of the structure is comparable with examples of dwellings at Stonehall, Mainland and Knap of Howar, Papa Westray. Although excavations at Pool uncovered some early Neolithic structures in the 1980s, this is the first ‘classic’ early Neolithic house to be discovered in Sanday.”

A number of artifacts have been found in the remains of the house — pottery fragments, flint knapping debris, animal bones, Skaill knives — and they are all well preserved, which is particularly key for the bones because time, soil and the elements have chewed up organic remains at other Neolithic sites in Orkney. The rich red-brown floors in the house indicate they have a rich complement of organic remains for researchers to study in the lab.

A team from the University of the Highlands and Islands Archaeology Institute (UHI), the University of Central Lancashire (UCLan) and specialists from other institutions have been excavating the site since mid-August using a geophysical survey and midden finds from a previous exploration as their guide. When the site was discovered by UHI and UCLan researchers in November of last year, their survey found evidence of a large settlement they thought might date to the Late Neolithic or Early Bronze Age (c. 2500-2000 BC). This was a transitional period which saw a great deal of social upheaval in Northern Scotland, so archaeologists were excited at the prospect of discoveries from so significant a time. If the dating on the Neolithic structure proves accurate, even though it will be earlier than expected nobody will be disappointed because it such a rare find in unusually good condition.

Sandy beaches are never easy to excavate, and the team has to do battle with the constant erosive action of wind and water. To top it off, the site is in the intertidal zone which means it is fully submerged twice a day. With less than a month to dig — the excavation is scheduled to end on September 8th — researchers are working assiduously to uncover as much of its archaeological material as they can.

The whales are an even more unexpected find, especially so many of them. The bones have been unearthed in two large cut pits. Local traditions suggest they are the detritus of a practice known as “ca,” from a word meaning “driven,” in which whales, dozens, even hundreds at a time, were chased towards the shore until they beached themselves. There they were butchered for their blubber, a valuable source of oil that was used in lamps, motors, soaps, even margarine. It smelled terrible burning, however, and I don’t even want to know what whale margarine tastes like, so when less unpleasant replacements were invented in the 20th century, the popularity of whale oil cratered.

The Cata Sand site is open to visitors. If you happen to be in the Sanday area, park in the parking lot and walk the western side to the highest dune. If it’s raining they won’t be there, but otherwise you can perch on the dude and see the excavation team at work.

Tomb of China’s Shakespeare found

Archaeologists excavating the site of a demolished factory in Fuzhou, Jiangxi Province, east China, have discovered the tomb of Ming Dynasty (1368-1644) playwright Tang Xianzu (1550-1616). A large grouping of tombs was first unearthed after the demolition of the old plant last year, 42 of them in total, 40 dating to the Ming Dynasty. Tomb M4 was identified as Tang’s from an epitaph, one of six found at the site some of which are believed to have been written by the playwright himself. His third wife Fu was buried with him in the tomb; his second wife Zhao was buried in the neighboring tomb labelled M3.

“The epitaphs can help us learn more about the calligraphy, art and literature in Tang’s time,” Xu [Changqing, head of Jiangxi Provincial Cultural Relics and Archeology Research Institute,] said.[…]

“This discovery is significant, because it tells us more about Tang’s life, his family tree and relationships with other family members,” said Mao Peiqi, vice chairman of the Chinese Society on Ming Dynasty History.

“Besides, by learning about the status and lives of Tang’s family, we can learn about education, culture and agriculture in the Ming Dynasty as well as the development of society,” he said.

Tang’s best known works are a series of plays known as the Four Dreams. One of them, The Peony Pavilion, is considered his masterpiece. It was the most popular play of the Ming Dynasty and continued to be performed in the classical Chinese opera tradition uninterrupted for hundreds of years until the present. Updated, experimental versions as well as the traditional style have been performed all over the world. There are references to it in popular music, novels, television and film.

Tang Xianzu and William Shakespeare died the same day: April 23rd, 1616. They had other things in common: exceptional lyrical qualities in their verse, themes of star-crossed romance, plot-driving dreams, ghosts, comical elements combined with the tragic and dramatic, historical settings and personages, and legacies as literary giants that loom large in their native countries and beyond. Because they were contemporaries with such enduring cultural influence, comparisons between Tang and Shakespeare are rife. Tang is often referred to as the Chinese Shakespeare as shorthand to explain the enormity of his importance in Chinese theatrical history. Last year, the 400th anniversary of both men’s deaths, The Peony Pavilion was performed at Stratford-upon-Avon, birthplace of the Bard. This year, a statue of the two great playwrights standing side by side gifted to the Shakespeare Birthplace Trust by the city of Fuzhou in 2015 was unveiled in the garden at Shakespeare’s Birthplace in Stratford-upon-Avon.

The discovery of Tang’s tomb is exciting not just for what it can tell us about his personal life, Ming Dynasty history and culture, but also because until now there was no commemorative location linked to his life for his myriad fans to visit to pay their respects. An empty tomb was built in a Fuzhou park in the 1980s just so there’d at least be some kind of monument. Now the city plans to create a destination site where Tang Xianzu and his family were really buried that will attract tourists, fans, artists and scholars alike.

Misunderstood dodo gets its due

A new study of bone sections has revealed new information about the life and reproductive cycles of the dodo bird. Because very few skeletal remains of dodo’s have survived, researchers have been reluctant to slice and dice them to use the latest technology that might discover more about a very misunderstood animal. Recent discoveries of bone fragments gave scientists at London’s Natural History Museum and the University of Cape Town a rare opportunity to take a look inside the dodo.

According to evidence in the different layers and types of tissue of the 22 bones examined, the dodo seems to have adapted its lifestyle to Mauritius’s stormy summer, from November to March.

During this period, heavy rain and strong winds can strip trees of leaves, flowers and fruit, causing severe food shortages for the island’s animals.

The dodo bones show repeated lines of arrested growth, which the researchers suggest correspond to the harsh conditions of the summer months when the birds were starved of food. […]

In common with many modern birds living on the island, the breeding season for dodos appears to have begun around August. Once chicks hatched, they grew quickly to almost adult body size, attaining sexual maturity before the stormy summer began.

Moulting began after the summer had passed, around March, with the replacement of the feathers of the wings and the tail. By July, the moult would have been completed and the bird would have had a chance to fatten up, ready for the next breeding season to begin.

The study has been published in the journal Scientific Reports and can be read free of charge here.

The dodo has become an icon of species extinction, unfairly painted as a clumsy weirdo who couldn’t find a way to survive, when, as this new evidence underscores, it was very well adapted to its unique environment before people hunted it mercilessly and destroyed its ecosystem. A native species of the island of Mauritius in the Indian Ocean, the dodo’s large beak and rotund body gave it something of a comical appearance which has played into the narrative of the goofy bird who just couldn’t hack in the real world.

It was the Dutch they couldn’t survive. Dutch ships first made landfall on Mauritius in 1598. Forty years later, the Dutch established their first settlement to harvest the island’s ebony trees. They also attempted to grow sugar cane and introduced domestic animals and deer. None of these endeavors proved financially successful and the first colony was abandoned two decades years after its founding. Some desultory attempts to colonize the island ensued until the Dutch gave up once and for all in 1710.

They sure left their mark, though. They destroyed the ebony forests, depriving endemic species of their habitat. They slaughtered local birds and turtles for food, and overwhelmed the ones they didn’t eat with competing animal species. One of those local birds was the dodo. The last living one was sighted in 1662 and the Dutch cared not one whit, so little, in fact, that they didn’t even notice that by the early 1690s the entire species was gone, extinguished in less than a century.

For a long time the dodo was considered mythical and the only evidence that it had ever existed were a few drawings made from life by explorers and a smattering of bones. The 19th century saw a sudden surge of interest in the curious bird, but there was so little to go on that scientists had to make do with a few drawings and random body parts. In their 1848 monograph The Dodo and Its Kindred, Strickland and Melville remarked on how difficult scientific study of a bird that had gone extinct less than two centuries earlier was because the source material was so sparse and unreliable.

In the case of the didinae, it is unfortunately no easy matter to collect satisfactory information as to their structure, habits, and affinities. We possess only the rude descriptions of unscientific voyagers, three or four oil paintings, and a few scattered osseous fragments, which have survived the neglect of two hundred years. The paleontologist has, in many cases, far better data for determining the zoological characters of a species which perished myriads of years ago, than those presented by a group of birds, which were living in the reign of Charles the First.

The first dodo fossils were found in 1865, but they were fragmentary. Research based on those finds that was published in science journals still had to rely heavily on speculation to fill in the many unknowns about this bird. Amateur naturalist Etienne Thirioux was the first to discover complete or almost complete skeletal remains of dodos during his excavations in Mauritius between 1899 and 1910. Decades after the Dodo became a subject of fascination despite the lack of osteological material bemoaned by Strickland and Melville, Thirioux’s finds made little impact on the scientific community. One Thirioux skeleton, almost complete minus a few bones, wound up in the Durban Natural Science Museum in South Africa. The second is in the Mauritius Institute, appropriately enough. The one in the Mauritius Institute is the only complete dodo skeleton known and the only one that is from a single bird. The Durban skeletal is believed to be a composite of two partial dodo skeletons.

Neither museum realized what rare and significant specimens they had until a few years ago when the Natural History Museum’s Dr. Julian Hume sought them out to do the first comprehensive study of dodo anatomy in 150 years. The study was capped off with this nifty 3D laser surface scanning reconstruction of the skeleton at the Durban Natural Science Museum shows a detailed rendering of the bird’s skeletal structure in what scientists now believe is an anatomically accurate position.
