The Homeric poems describe Achæans, Pylians, and Epeians, in Peloponnêsus, but take no notice of Ionians in the northern district of Achaia: on the contrary, the Catalogue in the Iliad distinctly includes this territory under the dominions of Agamemnôn. Though the Catalogue of Homer is not to be regarded as an historical document, fit to be called as evidence for the actual state of Peloponnêsus at any prior time, it certainly seems a better authority than the statements advanced by Herodotus and others respecting the occupation of northern Peloponnêsus by the Ionians, and their expulsion from it by Tisamenus. In so far as the Catalogue is to be trusted, it negatives the idea of Ionians at Helikê, and countenances what seems in itself a more natural supposition,—that the historical Achæans in the north part of Peloponnêsus are a small undisturbed remnant of the powerful Achæan population once distributed throughout the peninsula, until it was broken up and partially expelled by the Dorians. The Homeric legends, unquestionably the oldest which we possess, are adapted to a population of Achæans, Danaans, and Argeians, seemingly without any special and recognized names, either aggregate or divisional, other than the name of each separate tribe or kingdom. The post-Homeric legends are adapted to a population classified quite differently,—Hellens, distributed into Dorians, Ionians, and Æolians. If we knew more of the time and circumstances in which these different legends grew up, we should probably be able to explain their discrepancy; but in our present ignorance we can only note the fact.
