The central characters of the epic, such as Odysseus, Achilles, Agamemnon and Hector, are traditionally considered fictional figures from folklore, but aspects of the Homeric story may have some basis in actual historical events or people.
This, and the extremely detailed geographic descriptions in the epic itself, have invited investigation of the possibility that Homer's heroes might have existed and that the location of the sites described therein might be found.
Many locations around the Mediterranean were claimed to have been the heroes' "homes", such as the ruins at Mycenae and the little hill near the western Turkish town of Hissarlik.
Schliemann's work and excavations proposed, to a very sceptical world, that Homer's Agamemnon had lived at Mycenae, and that "Troy" itself indeed had existed at Hisarlik.
Each approach to identifying a location has been different, varying in degrees of scientific procedure, empirical investigation, informed hypothesis, wishful thinking, fervent belief, and sheer fantasy.
