Interesting comments.
We have been aculturated to think of the Homeric Greeks as some kind of heroes when they would more accurately be considered as ancient Vikings farming part of the year and raiding/trading during other times. Maybe not as murderous as the Norsemen but slavers and, as you said, pirates.
They enjoyed a good raid. :') They lived settled lives, but like the Scandinavians, they were mostly caught between mountains and the sea. There was a (natural) climate peak, followed eventually by a cooling. There was a population explosion (again, like the Vikings), one result of which was
the Lake Copais project, so they weren't just pirates. :')
The Mycenaean period ended by invasion, not all that long after the Trojan War. The pantheon of deities had changed by the time writing reemerged, and the more familiar alphabetic writing system arrived.
