This is a picture I personally took of a reconstructed Minoan mural in Crete. It’s a Minoan runner competing with Africans. The Mycenaeans could have at least met black people, unlike time traveling Viking longboats. Far from the worst inaccuracy.
The odyssey movie is using a Viking ship for the Mycenaean Greeks but racist people are claiming to be experts on historical accuracy when they are mad about an actress being black.
