Fossils of new giant carnivore species found in Kenya museum cabinet

Saturday, April 20th, 2019

Paleontologists have discovered the remains of a new species of carnivore mammal in a drawer at the National Museums of Kenya.  Fossils of a jaw, fragments of skull and pieces of the skeleton were unearthed in western Kenya between 1978 and 1980 by researchers looking for ancient primate remains. As the 22-million-year-old bones clearly did not come from apes, they were put in a cabinet and largely ignored until 2013 when Ohio University paleontologist Dr. Matthew Borths spotted them in a cabinet marked “hyenas” and realized they could be highly significant.

Borths contacted Ohio University paleontologist Dr. Nancy Stevens and she told him she’d noticed the unusual specimen as well while doing research in Nairobi. They teamed up and returned to the Nairobi National Museum in 2017 to study and analyze the fossils.

They named the species Simbakubwa kutokaafrika. With giant canine teeth the size of a banana, a skull as big as a rhinoceros and a body larger than a polar bear, the carnivore was far bigger than any of the big cats roaming the earth today.

“Opening a museum drawer, we saw a row of gigantic meat-eating teeth, clearly belonging to a species new to science,” says study lead author Borths. […]

Simbakubwa is Swahili for “big lion” because the animal was likely at the top of the food chain in Africa, as lions are in modern African ecosystems. Yet Simbakubwa was not closely related to big cats or any other mammalian carnivore alive today. Instead, the creature belonged to an extinct group of mammals called hyaenodonts.

Hyaenodonts were the first mammalian carnivores in Africa. For about 45 million years after the extinction of the non-avian dinosaurs, hyaenodonts were the apex predators in Africa. Then, after millions of years of near-isolation, tectonic movements of the Earth’s plates connected Africa with the northern continents, allowing floral and faunal exchange between landmasses. Around the time of Simbakubwa, the relatives of cats, hyenas, and dogs began to arrive in Africa from Eurasia.

Modern carnivores have one pair of meat slicing teeth in the back of the jaw. Hyaenodonts had three, so that made them highly effective meat cutters. They were hypercarnivores, animals that get more than 70% of their food from meat.

The newly identified species  Simbakubwa is the oldest species of gigantic hyaenodonts known, and its origin in Africa indicates gigantic hyaenodonts first evolved in Africa and then spread to Asia and Europe. They went extinct in the Miocene, about five million years ago, after millions of years of drastic changes in the ecosystem due to a drying climate. As apex predators, the gigantic hyaenodonts would have been fewer in number than other animals and highly reliant on a stable populations of prey.  Take away that 70+% meat and the carnivore quickly dies off.

“This is a pivotal fossil, demonstrating the significance of museum collections for understanding evolutionary history,” notes Stevens, Professor in the Heritage College of Osteopathic Medicine at Ohio University and co-author of the study. “Simbakubwa is a window into a bygone era. As ecosystems shifted, a key predator disappeared, heralding Cenozoic faunal transitions that eventually led to the evolution of the modern African fauna.”

The study has been published in the Journal of Vertebrate Paleontology and can be read online in its entirety.

Treasures emerge from Rijksmuseum storage

Friday, April 19th, 2019

The Rijksmuseum is showcasing some of the humble magnificence from its storage depot. This group of domestic and everyday use objects haven’t been on display for at least a hundred years, overshadowed by the museum’s extraordinary collection of masterpieces.

They’re getting their moment in the sun thanks to the Netherlands Collection Centre , a new shared storage building currently under construction in Amersfoort which will maintain the stored treasures of the Rijksmuseum, Paleis Het Loo, the Dutch Open Air Museum and the Cultural Heritage Agency of the Netherlands all in one state-of-the-art facility. To prepare for the move, the Rijksmuseum is revising their inventory entries for each piece, taking new photographs and writing new descriptions.

The objects range in date from the Middle Ages to the 19th century and will be displayed in five different galleries. The Middle Ages are represented by the museum’s entire collection of bronze mortars and pestles, used in pharmacology and perfume-making and for grinding spices in the home. The oldest mortar is a marquetry red copper and niello piece made in Khorasan, Persia, between 1100 and 1225. It is octagonal on the outside and cylindrical on the inside. The rest of the collection are of European, mosty Dutch, manufacture and decorated with all kinds of motifs from florals to lion heads to saints and hearts and slightly threatening studded ribs.

The Dutch Golden Age, so often associated with great artworks by the likes of Rembrandt, is viewed through a homier perspective in 17th century fireplace and kitchen bricks and tiles and cast iron firebacks. They performed an important function, protecting homes from areas of open flame, but that’s no reason not to make them a beautiful adornment as well. If I didn’t love my kitchen and fireplace as they are, I would be sorely tempted to get my mastic on and cover every conceivable surface with them. I mean, Scipio and Hannibal glowering at each other across a roaring fire? Yes please.

We may think of them as relatively mundane objects today, but when the mirrors in this collection were made in the 16th through 19th centuries, they were extremely expensive in materials, craftsmanship and human life as toxic mercury was essential to the process. This is reflected in their frames, which featured elaborate gilding, carving, molding and marquetry inlay. Some aren’t even looking glasses, but rather used as a striking medium for portraiture.

Small in size but not in stature are textile samples from 19th and early 20th century designers. Fabric swatches by Theo Nieuwenhuis, a student of Pierre Cuypers, architect of the Rijksmuseum whose design paid a great deal of attention to interior decoration with colorful, highly patterned wall frescoes and furnishings, are examples of the upholstery and wall textiles that once adorned Amsterdam’s Shipping House and other important city buildings. Most of the original interiors were discarded and replaced when fashions changed or they wore out.

Because the Rijksmuseum is very kind to those of us not fortunate enough to have regular access to it, almost all the objects on display in this exhibition have been collected in a Rijkstudio gallery so we can browse them online.

Scala Sancta unboxed

Thursday, April 18th, 2019

The 28 white marble stairs said to have been trod upon by Jesus during his trial before Pontius Pilate have been unveiled for the first time in three centuries. Church tradition holds that the staircase led to the prætorium of Pilate and was brought from Jerusalem to Rome by Helen, mother of Constantine, in 326 A.D.

(There’s no way they were the authentic prætorium stairs, just for the record. There was no marble in Palestine, and Rome would certainly have not gone to the expense of importing the high quality Aegean marble these stairs were made of for a backwater governor’s headquarters. Besides, Titus destroyed Jerusalem in 70 A.D., Pilate’s prætorium included. Helen was sold many, many “relics” on her tour of the Holy Land.)

They were installed in the Lateran Palace, the ancient domus of the Plautii Laterani family on the Caelian Hill which was given to the Pope by Constantine around 313 A.D., leading up to a hall near the Chapel of St. Sylvester. They were protected with a dedicated roof and regular steps were built on either side for non-ceremonial use.

The Lateran Palace was the primary residence of the popes until the 14th century when the papal court was moved to Avignon. By the time the long Babylonian Captivity was over and the papacy returned to Rome in 1377, the Lateran had suffered extensive damage in two major fires and the popes looked elsewhere for digs, eventually winding up in the Vatican.

Today, the Scala Sancta leads to the Sancta Sanctorum, the first private papal chapel which is known as the Holiest of Holies due to the numerous relics secreted there none of which have been seen since the early 16th century. The sanctuary is one of several buildings of the Lateran complex which includes the palace and the Basilica of St. John in Lateran, the titular seat of the Bishop of Rome. The Sancta Sanctorum is the only surviving section of the original ancient Lateran Palace, demolished by Pope Sixtus V in 1586 to make way for the much smaller one that stands there today. (Sixtus V was notorious for razing ancient monuments to the ground for use as raw material in his ambitious programs of architectural modernization.) He had the steps moved to the base of the Sancta Sanctorum and opened them to the public for the first time.

The steps and chapel became a major site of pilgrimage, with pilgrims ascending the stairs on their knees, kissing three spots marked with a cross said to be stained with droplets of Christ’s blood. So many pilgrim knees rubbed against the marble that they eroded deep troughs across the full width of each step. To keep the stairs from whittling down to nothing, in 1723 Innocent XIII had them covered them with walnut wood for their protection. Those casings remained in place for close to 300 years.

Restoration of the Holy Stairs began in January of 2018. Both the marble and the wood coverings required conservation, as did the frescoes on the side walls, so the Scala Sancta has been closed since work began. When restorers removed the wood, they were surprised to find deep furrows in the center of the steps. They realized these marks were left by the tips of millions of pilgrim shoes pushing up to the next step.

The conservation of the wood is not finished yet. The work on the marble steps, however, is complete, so Church authorities decided to open them to the public for a very short period from April 11th until June 9th, the day of Pentecost. Orthopedists can go ahead and buy that new Mercedes, because pilgrims are flocking to the Scala Sancta to take advantage of the opportunity. Oh, and there are plenary indulgences on the line for anyone who goes up the stairs on the knees in prayer after taking Communion and Confession.

 Three medieval crosses, set into the marble to commemorate that event, will now become visible again: the first in porphyry at the beginning of the staircase, another in bronze at the end, and the third on the eleventh stair, where according to tradition Jesus fell, breaking the marble with His knee.

Under the technical and scientific direction of the Vatican Museums, with the contribution of the Patrons of the Arts in the Vatican Museums, the restorers have brought to light the ancient marble, gathering from under the wooden cover a multitude of written notes, ex voto, coins and photographs left by the faithful, and now conserved by the Passionist Fathers who since 1853 have safeguarded the Shrine, at the behest of Pope Pius IX.

Water works unearth Iron Age ritual burials

Wednesday, April 17th, 2019

Excavations at the site of a water pipe installation have discovered 26 ancient skeletons, some from the Iron Age with unusual burial practices that suggest a ritual purpose. The new water pipes are being installed near Wantage in Oxfordshire to protect Letcombe Brook, a rare chalk stream in the Vale of White Horse which has been under environmentally damaging pressure from the water needs of agriculture and population.

With the Uffington White Horse, the  iconic Iron Age chalk hill figure, just five miles away, the site was archaeologically surveyed before the pipe installation. Contractors Cotswold Archaeology excavated several sites in the area where the 3.7 miles of pipe were set to be laid. They unearthed 26 individual burials dating from the Iron Age and the Roman period. They also found the remains of animals, household objects, pottery, cutting tools and one comb.

Unusually for the period, the Iron Age skeletons were buried in pits. There are very few surviving graves from this time, between two and three thousand years ago, because many of the Iron Age communities in the area are believed to have practiced  a form of sky burial in which bodies are placed in the open air to decompose courtesy of the elements and scavenging animals. Some of the pit burials featured peculiar body placement, a head between the feet, for example, and feet relocated to the upper body. Iron Age pit burials appear to have had a ritual purpose, and previous discoveries show evidence of bones having been exhumed at later dates.

“The Iron Age site at Childrey Warren was particularly fascinating as it provided a glimpse into the beliefs and superstitions of people living in Oxfordshire before the Roman conquest. Evidence elsewhere suggests that burials in pits might have involved human sacrifice.

Paolo Guarino, Cotswold Archaeology project officer, added: “These findings open a unique window into the lives and deaths of communities we often know only for their monumental buildings, such as hillforts or the Uffington White Horse.

“The results from the analysis of the artefacts, animal bones, the human skeletons and the soil samples will help us add some important information to the history of the communities that occupied these lands so many years ago.”

The human remains and archaeological material have been removed from the site by Cotswold Archaeology. They will be examined in laboratory conditions while Thames Water lays the new pipes which will supply groundwater taken from the Thames to neighboring villages thereby preserving Letcombe Brook’s unique ecosystem.

Notre Dame stands

Tuesday, April 16th, 2019

The roof is gone, the spire is gone, but the north and south towers of Notre Dame have withstood the conflagration. The rose windows survived, which is a freaking miracle. I thought they were goners for sure. The bells, including the great 13-ton bourdon Emmanuel, the only bell of Notre Dame to survive the cultural holocaust of the French Revolution, are intact. The artistic and religious treasures it held are safe in an undisclosed location.

Watching that spire collapse was so deeply horrifying I still can’t stand to recollect it, but it could have been so, so much worse, as in burned to the ground worse. The statues on the roof, which would have melted into puddles for sure, were removed prior to the beginning of the restoration work on the spire that was ongoing when the fire broke out.

The damage is massive and quite literally irreplaceable in the case of the wooden beams that formed the structure of the roof. They were cut down in the 13th century and there haven’t been any trees left that size in France for hundreds of years. It’s traumatizing to confront that level of loss. What’s gone is gone for good.

At the same time, the soaring Gothic majesty of that wood framing is the reason why the fire burned so thoroughly. Lots of oxygen, lots of combustible fuel, no way to break the fire, no way to fight it from the inside. Whatever architectural solution is devised to reconstruct the roof, I imagine fire security will be a top priority.

The church is owned by the state with the Church having rights of use. In the past this arrangement has caused lots of delays and nonsense when it came to restoration, but the agony of yesterday’s events will, one hopes, remain perpetually sharp and the outpouring of support — French billionaires have already pledge $339 million to the repairs — will keep attention fixed on bringing Notre Dame back.

My mother reminded me when we spoke just after the spire fell that when we lived in Rome many decades ago, a fire raged through St. Paul’s Outside the Walls, my favorite church when I was a kid. She said you could hear the stone cladding explode in the heat. St. Paul’s is far more modest in size and height than Notre Dame, and still the fire burned so viciously that it turned marble into artillery shells. Today it is more beautiful than ever, its gold facade gleaming even brighter than when I was a child with my face pressed against the window of the car to see the brilliant glow of the sun reflect against the mosaic every time we drove by it.

A reminder of what Notre Dame’s bells sounded like when her new ones were inaugurated just over six years ago. They will sound again. Between 43:20 – 45:18 all ten tower bells were rung along with the three in the spire, now lost forever.

(Between 12:15 – 21:50 the ten tower bells are rung in groups from largest to smallest. At 58:12 is the “Grand Solemnity,” beginning with Emmanuel followed by Marie and then the eight smaller ones.)

Nero’s Domus Transitoria opens to public

Saturday, April 13th, 2019

Nero was so closely associated with his insanely huge Golden Palace on the Oppian Hill that his previous abode, the Domus Transitoria, was entirely eclipsed by its successor. It was called the Transit House because it extended from the Esquiline to the Palatine so the imperial family could move from one hill to the other moving solely through the buildings, gardens and pools of his private 9,000 square foot palace. It too was constructed of opulent materials from patrician estates that had gradually fallen into imperial hands and was considered obscenely luxurious when it was built in the 50s A.D. It burned down in fire of 64 A.D. and Nero took advantage of the destruction of large swaths of the city to build the Domus Aurea by way of replacement.

The first remains of the Domus Transitoria were discovered in 1721 by the noble Farnese family. Like with the Domus Aurea, it was the surviving frescoes that caught the eye, their small fantastical details inspiring artists in the grottesque style. The Farnese helped themselves to whatever they wanted and what they wanted was those frescoes. They were chiseled off the walls and wound up in the collection of the Archaeological Museum of Naples. Most of what’s left of the palace — a triclium surrounded by porphyry columns, opus sectile floors, vaulted ceilings, an elegant nymphaeum, a communal latrine facility that sat 50 and is believed to have been built for the work crews who built the Domus Aurea after the fire — was excavated by Giacomo Boni in the 1910s.

The Domus Transitoria has never been open to visitors before, but after a decade-long program of structural reinforcement and renovation, you can now descend into the ruins of palatial rooms and gardens that were once ground level. As with the phenomenal Domus Aurea tour, there’s a virtual reality component here too.

Visitors receive virtual reality goggles which bring the dank chambers to life, showing them as they were 2,000 years ago – part of a huge palace decorated with marble pillars, lavish frescoes, mosaic floors and fountains.

The walls were painted with garden scenes, including trees, flowers and song birds.

Inspiration for the design of the sumptuous residence came from a palace built for the Egyptian pharaoh Ptolemy in Alexandria, said Alfonsina Russo, the director of the archeological zone that encompasses the Roman Forum, the Colosseum and the Palatine Hill.

“It reflects the personality of Nero, one of the most controversial figures of the Roman Empire,” said Prof Russo.

The Archaeological Museum of Naples has loaned the frescoes looted from the palace in the 18th century for the reopening. The Palatine Museum just a few steps away has a few frescoes of its own removed in the 1950s as well as statues and other decorative pieces recovered from the Domus Transitoria.

The tour of the Domus is included in the new Roman Forum-Palatine ticket (16 euro) which is valid for a day. The Domus Transitoria can only be visited from Friday to Monday. Included in the price of the ticket is entry to the Palatine Museum, the Neronian Cryptoporticus, the Domus of Augustus, the Domus of Livia, the Temple of Romulus, Santa Maria Antiqua and the imperial ramp of Domitian. You have no idea how hard I tried to get into Santa Maria Antiqua and Domitian’s ramp my last two visits to Rome. No one’s keeping me away next time.

Stolen de Kooning conservation, plus a crazy twist

Friday, April 12th, 2019

Woman-Ochre, the hugely valuable painting stolen from the University of Arizona Museum of Art in 1985 and rediscovered in the modest home of a New Mexico couple after their estate was sold in 2017, is being restored by conservators at the Getty Museum and specialists at the Getty Conservation Institute. Cut out of its frame and rolled up by the thieves, then crudely stapled to a frame, the canvas was in poor condition when it was recovered. The University of Arizona has wisely decided to bring in the heavy artillery in the form of Getty experts.

The Getty is well versed in the work of de Kooning, whose idiosyncratic working methods have created intense speculation and debate among conservators and art historians, primarily from visual inspection and anecdotal accounts rather than rigorous technical analysis. In 2010, the Conservation Institute worked closely with Susan Lake, then head of collection management and chief conservator at the Hirshhorn Museum and Sculpture Garden in Washington D.C., on an in-depth study of de Kooning’s paintings from the 1940s through the 1970s, published by the Getty as Willem de Kooning: The Artist’s Materials.

The Getty-University of Arizona project will also be a teaching tool, providing access and information to graduate-level conservation and science students at local universities as well as those from the University of Arizona.

The restoration begins this month and is expected to take about two years. The painting will be briefly displayed at the Getty Museum in 2020 before returning home to the University of Arizona.

In the meantime, the investigation into the theft continues. The FBI won’t comment on the case until they’ve completed their investigation, but there is new information from non-law enforcement sources, and y’all, this is a crazy, CRAZY story.

Quick recap: November 29th, 1985, the day after Thanksgiving, a man and a woman entered the UofA Museum of Art in Tucson. The woman distracted the security guard while the man cut Woman-Ochre out of its frame, rolled it up and hid it under a coat. Fifteen minutes after walking in the door, the couple walked out and neither they nor the painting they stole were seen again for 32 years.

In August of 2017, David Van Auker, Buck Burns and Rick Johnson, owners of Manzanita Ridge Furniture & Antiques in Silver City, New Mexico, bought a bunch of stuff from the estate of Jerry and Rita Alter in Cliff, New Mexico, for $2000. Jerry, a retired music teacher, had died in 2012. Rita, a retired speech pathologist, died in June 2017. After her death, her nephew and executor of the estate, Ron Roseman, put the contents of their house up for sale.

It was customers of Manzanita Ridge Furniture & Antiques commented that the de Kooning sure looked a lot like a real one. A little Googling and a call to the University of Arizona and the next thing you know, its authenticity was confirmed and the painting was on its way back to Tucson.

The rediscovery of a painting that a conservative estimate based on past sales of works from the series would value at something in the neighborhood of $150 million in a little ranch house in rural New Mexico made big news, of course. How had the Alters acquired it? Nobody in their family knew anything about it. It was hanging in their bedroom blocked by the door and could only been seen from inside the room. Ron Roseman didn’t even know it existed until January of 2017 when he was helping out his aunt as she struggled with dementia in her final months.

After the find made the press, Ron found an interesting photo when going through some old family pictures. It was of his aunt and uncle smiling as they spent Thanksgiving of 1985 with family. In Tucson. This is that picture:

This is a composite sketch of the thieves published in the Arizona Daily Star of December 5th, 1985:

The getaway car was a rust color. Except for one blue one at a different time, the Alters only owned red cars. The painting only shows evidence of having been reframed once after the theft, an amateur hack job using a commercial pre-made frame, not custom work. Van Auker said it was coated in thick dust and that the frame’s outline was marked on the wall when he removed it. He’s sure the painting had been fixed in that place for decades.

Yeah. And it gets crazier.

The Alters wrote three books together, one about traveling, another about poetry and a twist on Aesop’s Fables.

“The Cup and The Lip: Exotic Tales” features fictional accounts of travel adventures. In one story, “Eye of the Jaguar,” a grandmother and her granddaughter case a local city museum and then return to steal its prize exhibit, a 120-carat emerald.

The thieves leave behind no clues. The jewel is kept hidden “several miles away” from the museum, behind a secret panel, “and two pairs of eyes, exclusively, are there to see!” he wrote.

No fingerprints were left at the scene of the crime. There was no security video in the museum at that time. There is no hard evidence to be found more than three decades after Woman-Ochre was purloined. But it sure does look like the Alters might just have done the unthinkable and pulled a massive heist for the sheer pleasure of looking at an abstract expressionist nude until the day they died. Is it weird that I can’t help but admire that a little? I mean, I can’t deny having fantasized about snagging some amazing artifact or artwork and cooing over it in secret for centuries as it shriveled me up and extended my life unnaturally like Gollum.

Marie Antoinette’s rooms reopen at Versailles

Thursday, April 11th, 2019

In January of 2016, the Queen’s State Apartment, the grand rooms occupied by the Queens consort of France from Louis XIV’s wife Maria Theresa to the doomed Marie Antoinette, were closed to the public as part of the “Grand Versailles” project, a massive 17-year, €500 million program to restore, upgrade and improve the buildings and grounds of the palace. The Queen’s rooms were in need of significant conservation and upgrades to the fire safety systems, utility networks, air treatment and climate control.

The four adjoining rooms — the Queen’s Guard Room, the Royal Table Antechamber, the Nobles’ Room and the Queen’s Bedchamber — had been hard done by heat. King Louis-Philippe (r. 1830- 1848), seen here turning into a pear, had heaters blowing in the palace that were way too hot and couldn’t really be controlled. The heat of the summer was bad enough, raising the temperature at the highest point under the ceilings to 115F. A new climate-adaptive air system was installed with humidity regulation controls.

After more than three years of painstaking labour, the Queen’s State Apartment will reopen on April 16th. In order to replace the ductwork and pipes behind the walls, the decorative woodwork had to dismantled, bronzes and textiles removed. Carpenters, goldsmiths, the silk weaving house of Tassinari and Chatel and many other artisans and trades were involved in the reconstruction and restoration.

Extensive studies were undertaken to recreate the original paint schemes, restore textiles and other decorative elements. The rocaille decorations on the wall, a trompe-l’oeil technique that used plaster, rock and seashells to create the illusion of gilded swirls, crests and cupids, created for Marie Leszczynska, wife of Louis XV, was rediscovered under thick layers of overpaint. The delicate blue grey background paint has been restored making the faux gilded elements stand out again. A grisaille allegory by François Boucher’s representing the queenly virtues of charity, piety, liberality and prudence was restored to its original softness as well with the removal of discolored overpaintings and varnishes that had left the figures looking yellowed and flat.

Two exhibitions will open in the rooms on Tuesday dedicated to three queens who called this apartment home and gave birth to 19 princes and princesses of France there. Marie Antoinette has the biggest name recognition, but Marie Leszczynska (who I know almost nothing about beyond the fictionalized account in the awesomely entertaining and even more awesomely confusing anime Le Chevalier D’Eon) is finally getting a little attention too, as is Madame de Maintenon, morganatic wife of Louis XIV.

On a technically unrelated but in a weird way related note, the palace will be throwing a rave this summer in the Halls of Mirrors. It’s a celebration of French electronica label Ed Banger Records and will feature the label’s top four DJs spinning at the foot of the Hall of the Mirrors to the delight of crowds grinding it out on a massive dance floor that will be erected on the terraces of the Château de Versailles overlooking its impeccable gardens. Grab your gilded pacifiers and most rococo glow sticks and book your tickets for the June 8th event here.

Also, Google Arts & Culture has a nifty online exhibit called Sciences at Versailles that uses artworks and objects to explore the role technology, engineering, astronomy, geography and other scientific pursuits played at the courts of Louis XIV and his successors.

Sciences at Versailles chapter 1: science & power
Sciences at Versailles chapter 2: astronomy, queen of sciences
Sciences at Versailles chapter 3: discovering new worlds, geography
Sciences at Versailles chapter 4: cascade creation, water engineering
Sciences at Versailles chapter 5: botany & zoology, a taste for exoticism
Sciences at Versailles chapter 6: fit for a king, medicine and surgery
Sciences at Versailles chapter 7: the science show, physics and chemistry
Sciences at Versailles chapter 8: mechanics, automatons and hot-air balloons
