The Iliad is focused on the Siege of Troy, of course, which may have occurred near the end of the Mycenaean Age – at least the most likely dates make it seem that way. But there are inconsistencies too. For example in Mycenae the dead were buried, while in the Iliad they were cremated.
Geography is another interesting point of comparison. in the Iliad, Homer describes a catalog of ships from nine towns including Pylos. He also mentions nine areas of a “hither” province, but Pylos is not one of those. None of the names on these two lists match. When he describes Ithaca, the home of Odysseus, the geography is wrong, making it obvious he had never been there. He also places Mycenae on the southern shore of the Corinthian Gulf rather than inland from the Argolikos Gulf.
