Mycenaean Warriors

[hoplite14gr]

Well, first of all, I don´t think there is any proof that the war of Troy ever happened, is there any? but specifically on shields in Homer, I seem to recall that he says the shield of Achilles was made by Hephaistos himself, what for the credibility of such a source?

Well not the war as described by Homer or not the way that Homer understood it. But there are evidence of large wars and strife in the eastern mediteranean from 1250 to 1100.
The Trojan war is more widly known to the public because of the Homric epics.
But the operations in Cilicia, Syria, Cyprus have not so famous epics related to them as do the Dardamelle operations.
