After the Epirotæ and Illyrii follow the Acarnanes,[4] the Ætoli, the Locri-Ozolæ, then the Phocæenses and Bœoti, Grecian nations. Opposite to these on the other side of the strait is Peloponnesus, which comprises the Gulf of Corinth,[5] interposed between, and determining the figure of the latter, from which it also receives its own. Next to Macedonia[6] are the Thessalians,[7] extending as far as the Malienses,[8] and the other nations, situated on both sides of the isthmus. 2. There are many Greek tribes, but the chief people are equal in number to the Greek dialects with which we are acquainted, namely, four. Of these, the Ionic is the same as the ancient Attic; (for Iones was the former name of the inhabitants of Attica; from thence came the Iones who settled in Asia,[9] and use the dialect now called Ionic;) the Doric was the same as the Æolic dialect, for all the people on the other side of the isthmus except the Athenians, the Megareans, and the Dorians about Parnassus, are even now called Æolians; it is probable that the Dorians, from their being a small nation, and occupying a most rugged country, and from want of intercourse [with the Æolians], no longer resemble that people either in language or customs, and, although of the same race, have lost all appearance of affinity. It was the same with the Athenians, who inhabiting a rugged country with a light soil, escaped the ravages of invaders. As they always occupied the same territory, and no enemy attempted to expel them, nor had any desire to take possession of it themselves, on this account they were, according to Thucydides, regarded as Autochthones, or an indigenous race. This was probably the reason, although they were a small nation, why they remained a distinct people with a distinct dialect.
