Some of potentially oldest cave art so far found in Sulawesi, Indonesia:
From NewScientist (23 January 2021):
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.
Or they just liked bacon.
And that’s something about archaeologists interpreting artifacts: they don’t seem to think our ancestors had a sense of whimsy.
