Leaving out of account some settlements occupying a more isolated position--such as that of the Locrians with its offsets Hipponium and Medama, and the settlement of the Phocaeans which was not founded till towards the close of this period, Hyele (Velia, Elea)--we may distinguish in a general view three leading groups. The original Ionian group, comprehended under the name of the Chalcidian towns, included in Italy Cumae with the other Greek settlements at Vesuvius and Rhegium, and in Sicily Zankle (afterwards Messana), Naxos, Catana, Leontini, and Himera. The Achaean group embraced Sybaris and the greater part of the cities of Magna Graecia. The Dorian group comprehended Syracuse, Gela, Agrigentum, and the majority of the Sicilian colonies, while in Italy nothing belonged to it but Taras (Tarentum) and its offset Heraclea. On the whole the preponderance lay with the immigrants who belonged to the more ancient Hellenic influx, that of the lonians and the stocks settled in the Peloponnesus before the Doric immigration. Among the Dorians only the communities with a mixed population, such as Corinth and Megara, took a special part, whereas the purely Doric provinces had but a subordinate share in the movement. This result was naturally to be expected, for the lonians were from ancient times a trading and sea-faring people, while it was only at a comparatively late period that the Dorian stocks descended from their inland mountains to the seaboard, and they always kept aloof from maritime commerce. The different groups of immigrants are very clearly distinguishable, especially by their monetary standards. The Phocaean settlers coined according to the Babylonian standard which prevailed in Asia. The Chalcidian towns followed in the earliest times the Aeginetan, in other words, that which originally prevailed throughout all European Greece, and more especially the modification of it which is found occurring in Euboea. The Achaean communities coined by the Corinthian standard; and lastly the Doric colonies followed that which Solon introduced in Attica in the year of Rome 160, with the exception of Tarentum and Heraclea, which in their principal pieces adopted rather the standard of their Achaean neighbours than that of the Dorians in Sicily.
