The term “Mycenaean” is an archaeological label, applied to a particular complex of material culture from the Greek mainland that dates to the Late Bronze Age. “Mycenaeans” is a short hand, and should explictly not be taken to refer to a particular ethnic group, since we don’t know how people in the Bronze Age Aegean defined themselves.
For example, we don’t know if the people from the mainland – producers of “Mycenaean” material culture, however defined – even conceived of themselves as ethnically distinct from e.g. the contemporary people on Crete, who are often referred to collectively – and misleadingly – as the “Minoans”.
After Knossos, Invicta invited archaeologist Josho Brouwers to talk about Assassin’s Creed: Odyssey’s depiction of the citadel of Mycenae. They also talk a bit about some other major sites in the Argolid.
