Conserving the Met’s King Arthur tapestry

I can never get enough videos of conservators bathing a large but fragile historic tapestry ever so gently like it’s a little baby. This time the tapestry in question is “King Arthur” from the “Nine Heroes Tapestries” series that is in The Cloisters, the Metropolitan Museum of Art’s branch dedicated to medieval art.

In this tapestry, King Arthur sits on a throne under a canopy accompanied by two bishops on the bottom row, two archbishops in the middle and three cardinals on balcony overlooking them. They are set in a capriccio of Gothic architecture complete with tracery windows, pointed arches, rib vaulting and elaborate spires. The clothing and architecture is typical of around 1400.

The series was woven in the late 14th century is the South Netherlands and are some of the oldest surviving tapestries from the Middle Ages. They depict nine famous heroes, also known as the Nine Worthies, drawn from literature, history and scripture that were believed to embody the ideals of chivalry. They are Prince Hector of Troy, Alexander the Great, Julius Caesar, Joshua, David, Judas Maccabeus, King Arthur, Charlemagne and Godfrey of Bouillon (a French nobleman who became the first King of Jerusalem after he captured it in the First Crusade in 1099). Originally the nine heroes were woven into three separate tapestries, three on each, grouped by religion (pagan heroes on one, Jewish heroes on another, Christians on the third), but by the time they entered the Met’s collection in 1947, only five heroes had survived. It’s a miracle there are any left at all given the rough treatment they received. At some point they were cut up in dozens of pieces and survived as Frankenstein monsters of their former selves, the fragments stitched together in the early 20th century to be hung as curtains in an castle in France.

The Met’s curators were able to figure out how to puzzle the tapestries back together working only with photographs, but even with the jigsaw solved on paper, the hard work of disassembling and reassembling was still to be done. The museum engaged four women with great needle skills to transform those curtains back into plausible tapestries. They were Mathilda Sullivan, Helen O’Brien, Swiss immigrant Aline von Arx and Norwegian immigrant Olga Wangen Larsen. Restoration work began in December 1947 with Sullivan buying the wool threads they would need and was completed on May 15th, 1949, literally four days before they went on display for the first time in their new gallery at The Cloisters. Collectively the four worked just shy of 6,000 hours to piece the heroes back together.

None of the Nine Heroes series have received conservation treatment since 1949, and they are now in need of cleaning and stabilization. The cut-and-paste life they’ve led for centuries makes them extremely delicate, so the fewer interventions the better. “King Arthur” is the first of the series to be conserved. The rest will follow in his footsteps while conservators use the knowledge they’ve gained in this intervention to aid in the next.

Export bar for 14th c. ivory casket with Grail, wild men

An exceedingly rare French Gothic ivory casket carved with low relief scenes of Arthurian romance is at risk of leaving the UK if a museum or gallery cannot be found to acquire it for the assessed price of £1,506,000. The UK’s Arts Minister has placed a temporary export bar on the object to give local institutions the opportunity to raise the sum by March 1, 2023.

The casket sold at Edinburgh’s Lyon & Turnbull auction house in May 2021 for £1,455,000, a world record for a medieval ivory casket and the highest price any single object has ever sold for at an auction in Scotland. It is one of only nine of secular Gothic ivory coffrets known to survive, and almost all of them are in museums like the Louvre and the Metropolitan.

[Reviewing Committee on the Export of Works of Art and Objects of Cultural Interest] member Stuart Lochhead said:

This French 14th-century carved ivory casket is adorned with scenes of chivalry and romance including depictions of wild men – ranging from the rescue of a lady from one such assailant to a procession of knights and ladies who lead the captured wild men in chains. Similar iconography exists on some of the other nine known mediaeval caskets of this type, but it is the present one that illustrates some of the earliest and rarest type of images.

No disrespect to the honorable members of the RCEWA, but while they’re right about the wild men being particularly awesome on this example, I’m not sure that the scene on the top of the casket depicts the wild men attacking the Castle of Love. The usual iconography of the Castle of Love, a chivalric metaphor for seduction, is women arrayed along the crenellations while fully human knights launch catapults full of roses and scale the walls to breach the ladies’ “defenses.” The wild men on this coffer are both fighting knights defending the castle and kidnapping women (rather gently, really, almost like they’re saving them from the knights). Two lions guard two gates at the bottom of the castle. This strongly suggests it’s the Grail Castle of Corbenic, the home of the Holy Grail according to the 13th century French prose romance L’Estoire del Saint Graal, so this is likely the culmination of Galahad’s Grail quest only with a bunch of wild men in the melee.

The Grail makes a starring appearance on the right side panel. A kneeling angel holds it aloft before the arrayed Arthurian knights. Galahad, holding the magical sword he pulled from the stone, is in the center. Scenes from another Arthurian romance, the legend of Tristan and Isolde, on the left side panel and on the left two sections of the back panel.

Elephant ivory imported from Africa and Asia had been prized since antiquity for its lustrous, flesh-like glow and carvable surface. In medieval northern Europe, it was a luxury material reserved largely for religious objects (book covers, statuettes, reliquaries, croziers). Ivory supplies plummeted in the 12th century, only picking back up in the mid-13th century when Mediterranean merchants established a new water-going route through Gibraltar direct to the English Channel for the textile dye and ivory trade.

By the turn of the 14th century, the higher availability of ivory had lowered the price enough that a material once exclusive to liturgical use was now available for personal objects like mirrors, combs, cosmetics vessels and coffers. Instead of religious subjects, these objects were carved with secular motifs popular among the aristocratic buyers of such high-end toiletry items — courtly love, Arthurian romance, falconry, capturing a unicorn. The caskets are believed to have been romantic gifts used to store love tokens, letters, jewels, etc. We know in one specific case, that of Clemence of Hungary, Queen of France for less than a year between 1315 and 1316, that her carved ivory box contained a comb and mirror set and a chess set.

Gothic ivory carving reached its apex between 1230 and 1380 and Paris was the center of production with other capitals following the fashions and trends established there. The style of carving and manufacture indicates the Edinburgh coffret was made in a workshop in Paris around 1330. By the end of the 14th century, plague, war and economic upheaval had throttled the ivory supply and carved objects became more scarce again.

One of the other rare features of this casket is its long ownership history. It can be traced directly to the early 17th century. A genealogy of the Baird family of Auchmeddan Castle in Aberdeen records the chest in the possession of Thomas Baird, Fransciscan friar of a monastery in Besançon, France, some time after 1609. It remained in the Baird family, passing to descendants by marriage. One of those descendants was the seller who put it up for auction last year, so the casket has been in Scotland for 400 years. That was one of the factors in the Committee’s decision to recommend the export ban.

14th c. cog shipwrecks found in Sweden

The wrecks of two cogs dating to the middle of the 14th century have been discovered in Varberg, Sweden. The cogs were discovered this spring during an archaeological investigation in advance of a railway tunnel construction. The wooden remains were unearthed from what in the Middle Ages was the shoreline of the town of Getakärr (which charmingly means goat marsh), Varberg’s medieval predecessor. Cogs are rare finds and finding two of them 30 feet apart is unique.

The first Varberg cog is the largest and the best preserved. In fact, it is the best preserved cog ever discovered in Sweden. It consists of almost the entire port side of the ship, about 67 feet long and 16 feet wide, its ballast still in place. The second cog consists of the remains of a hull about 26 feet long and 15 feet wide. Examination of the vessels found that they were built with carvel planking (planks laid side to side creating a smooth surface) on the bottom and clinker built (overlapping planks) on the sides. The planks were sealed with moss and reinforced with crossbeams going all the way through to the exterior of the hull.

Dendrochronological analysis of the first timber samples from both ships has now been completed. The tree-ring analysis found that the wood from Varberg Cog 1 was felled in 1346 somewhere around the Netherlands, Belgium or northeastern France. The wood used to build Varberg Cog 2 was felled between 1355 and 1357 in northern Poland. This suggests they were not local ships, but had come from some distance. It is not yet clear what caused them to sink.

A number of daily use objects left by the crew were found in the excavation, preserved in the waterlogged soil of the shore. Archaeologists unearthed leather shoes, wooden utensils (spoons, bowls), barrel parts, and in Varberg Cog 1, they also found a significant amount of rigging, spare parts and other elements of the ships’ equipment. 

The wrecks have been laser scanned and 3D models created of them. Study of the ships is ongoing and will continue through 2023.

Original polychrome paint found on Duomo sculptures

Restoration of the marble reliefs on the north façade of the Duomo of Florence has revealed original polychrome paint on an exterior sculpture of Madonna and Child with Adoring Angels. The sculptures date to 1359-1360 and are mounted in an arched niche above the Porta dei Cornacchini, the door in the north wall of the cathedral. While the marble in the background is colorful — the Duomo is famous for the white, pink and green marble cladding that gives the cathedral its distinctive look — the sculptures themselves were previously believed to have been left the natural white of the marble.

The marbles of the north façade were in dire need of conservation, having suffered extensive erosion from rainwater runoff, deposits of surface dirt, black sulfurous encrustations and bird poop galore. Since restoration work began in September 2021, experts from the Opera di Santa Maria del Fiore have cleaned more than 10,000 square feet of marble. The process revealed extensive traces of the paint, including the brown iris of Mary’s left eye, the blue-green color inside her mantle, red on the outside of her mantle and a rich damask pattern on the garment worn by the Christ Child. This is the first time such large sections of polychrome paint have been found on an exterior sculpture of the Duomo. Previous finds were just tiny glimpses — a few dabs of gilding and light blue on other sculptures.

Earlier attempts at restoration did more harm than good to the original colors. A coating of brown oxalate applied directly to the surface of the marble in the 1950s has darkened over the decades, obscuring the traces surviving paint. Conservators removed the layer of fluorosilicate over the oxalate, but decided to keep the oxalate in place because it protects the surface of the marble even as it darkens it.

The museum has said that this sculpture group was most likely not the only one on the Duomo in polychrome, though now they appear to be marble white.

The find has led to the image of the Duomo as one in color, with white, green, and pink on the exteriors and red and gold mosaics on the facade.

“The exciting find of multiple colors of the figures on Porta dei Cornacchini of the Florence cathedral,” said Duomo museum director Timothy Verdon. “It reminds us that Florence at the end of the 14th century and beginning of the 15th was a very colourful city. The cathedral also had painted statues with gilding on the wings of angels and on clothing – thus, a celebration. A celebration that we forgot and are beginning to rediscover.”

Gold disc brooch found in 7th c. Basel grave

An excavation of the Kleinbasel neighborhood of Basel, Switzerland, has brought to light 15 graves, some of them richly furnished, from an early medieval burial ground. The presence of a burial ground from this period had been known since the 19th century, so a rescue archaeology excavation was undertaken in the area before installation of new utility pipes. Earlier this year the excavation unearthed the 6th century grave of a young girl buried with a dazzling array of about 380 beads. The recent discoveries prove that the cemetery was more densely populated than archaeologists realized.

One of the highlights of the newly-discovered graves is that of an elite young woman who was about 20 years old when she died in the 7th century. The grave was damaged during construction in the early 20th century. The skull is lost, as is the body below the knees, but the riches she was buried with remain. The grave contained a rare gold disc brooch made of a base plate made of a non-ferrous metal that was then topped with gold. The disc was then adorned with gold wire filigree and inlayed with green garnet gemstones and blue glass. The brooch likely held together a cloak, now gone, at her neck. She was also wearing a necklace made of 160 glass, amethyst and amber beads (or had them sewn onto the collar or bodice of her garment). There was also a leather strap decorated with metal crosses that terminates in a large amber pendant. Around her waist was a belt with an iron buckle and a silver tongue. Hanging from the belt was a chatelaine with pierced Roman coins, metal artifacts and a bone comb.

Other notable graves found in the current excavation include a child’s grave containing a large silver inlay belt buckle, metal belt fittings, scissors and a comb, and a stone cist grave containing the skeleton of an adult man. The man’s face bears the unmistakable evidence of violent blow from a sword. Amazingly, the man survived the disfiguring injury as he died after it was fully healed.

Basel was founded as a Celtic oppidium, or fortified settlement, in the 1st century B.C. The Romans built a military camp on the site of the settlement and by the end of the 1st century A.D., it was absorbed into the Roman province of Germania Superior. Roman control weakened in the 3rd century, but the troops along the Rhine managed to repel invasions from the Germanic Alemanni confederation several times in the 4th century. The Alemanni finally won around 406 A.D., settling throughout the Swiss Plateau. They and the Franks after them occupied the old Roman castle and the town’s fortunes were revived. It was minting its own coins in the 7th century and was made a bishopric in the 8th. The Roman castle was converted into Basel’s first cathedral. What is today the Kleinbasel area was the castle/cathedral hill, the nucleus of the early medieval settlement.
