Archaeologists worked with primatologists to re-examine wall-paintings of monkeys in a Minoan building buried in volcanic ash around 1600 BCE. at the site of Akrotiri, which is located on the Greek island of Thera in the Aegean Sea. No monkeys are known to have lived in Greece at the time. Most of the monkeys in the painting have been identified as olive baboons, which are native to Egypt, but one monkey, with distinctive fur and an S-shaped tail, was identified as a grey langur, a species that lives in Nepal, Bhutan, and the Indus Valley of India.
It was already known that the Minoans had contact with Egypt. And this wall mosaic hints at contacts with the Indus River Valley civilization, as well. Or perhaps it demonstrates the far-reaching and interconnected nature of the trade networks even in the Bronze Age.
