The ancients wrote that there were two places of the name of Dodona, one in Thessaly, in the district of Perrhaebia near Mount Olympus, and the other (the Thesprotian Dodona) in Epirus in the district of Thesprotia.
The Thessalian Dodona is mentioned in the Catalogue of Ships in the Homer's Iliad along with Cyphus, Gonnos, and the "banks of the Titarisios", all ruled by Guneus, and belonging to the Enienes and Peraebi.
[2] These places and ethnic groups are all located in ancient Thessaly, not Epirus; and thus, there can be no doubt, that this passage in Homer refers to the Dodona in Thessaly.
[3] However, the other Dodona, and its oracle which Odysseus consulted, is mentioned by Homer in the Odyssey.
[6][7] As there is no evidence of the existence of an oracle at the Thessalian Dodona, it is probable that the prayer of Achilles was directed to the god in Epirus, whose oracle had already acquired great celebrity, as we see from the passage in the Odyssey.
