Proto-Ionians
The Proto-Ionians are the hypothetical earliest speakers of the Ionic dialects of Ancient Greek, chiefly in the works of Jean Faucounau. The relation of Ionic to the other Greek dialects has been subject to some debate. It is mostly grouped with Arcadocypriot as opposed to Doric, reflecting two waves of migration into Greece following the Proto-Greek period, but sometimes also as separate from Arcadocypriot on equal footing with Doric, suggesting three distinct waves of migration.
