The mode of fighting in the Homeric epics is also wholly different from what one might expect from a state-society like the Mycenaean kingdoms. The Homeric heroes are leaders of smallish warbands; raiding and piracy were common activities for them, as demonstrated by the lying stories of Odysseus. Hans van Wees has examined the nature of warfare in the Homeric epics and found them to be very similar to the style of fighting employed by tribesmen on Papua New Guinea; see, for example, his Greek Warfare: Myths and Realities (2004), pp. 153–156 and 160–162, as well as plates XIV–XVII. This was the type of warfare that Homer was familiar with; for the Iliad, he simply made everything larger and the armies more numerous, while leaving the rest more or less the same.
