Very old warty pigs

This is quite something:

Stunning cave paintings discovered in Indonesia include what might be the oldest known depictions of animals on the planet, dating back at least 45,000 years.

The paintings of three pigs, alongside several hand stencils, were discovered in the limestone cave of Leang Tedongnge on the Indonesian island of Sulawesi. Even local people were unaware of the cave sites’ existence until their discovery in 2017 by Adam Brumm at Griffith University, Australia, and his team.

“I was struck dumb,” says Brumm. “It’s one of the most spectacular and well-preserved figurative animal paintings known from the whole region and it just immediately blew me away.”

Sulawesi is known to contain some of the world’s oldest cave art, but the new paintings may predate all other examples so far discovered on the island.

Brumm and his colleagues used a technique called uranium-series dating to analyse a mineral formation that overlapped part of the image, and that must have formed after the cave art was produced. The mineral formation is at least 45,500 years old, suggesting the artwork itself could be much older.

“It adds to the evidence that the first modern human cave art traditions did not arise in ice age Europe, as long assumed, but at an earlier point in the human journey,” says Brumm.

Each of the three pigs is more than a metre long. The images were all painted using a red ochre pigment. They appear to be Sulawesi warty pigs (Sus celebensis), a short-legged wild boar that is endemic to the island and is characterised by its distinctive facial warts. “This species was of great importance to early hunter-gatherers in Sulawesi,” says Brumm.

These pigs appear in younger cave art across the region, and archaeological digs show that they were the most commonly hunted game species on Sulawesi for thousands of years. “The frequent portrayal of these wild pigs in art offers hints at a long-term human interest in the behavioural ecology of this local species, and perhaps its spiritual values in the hunting culture,” says Brumm.

I don't know why they're always so keen to talk about spiritual values, these archaeologists. Perhaps because we like to think art is one of the highest human faculties, and so we assume the paintings must have served some sublime higher purpose. My own theory, yet to be confirmed or indeed postulated till now, is that this is like that Pompeii fast food joint they unearthed recently: it's a very early hog roast site. "Get your warty pig steaks here!" type of thing. "Tenderest in all Sulawesi! Melts in the mouth or your glittery beads back!"
