As for the Ionians, the reason why they made twelve cities and would admit no more was in my judgment this: there were twelve divisions of them when they dwelt in the Peloponnese , just as there are twelve divisions of the Achaeans who drove the Ionians out— Pellene nearest to Sicyon ; then Aegira and Aegae , where is the never-failing river Crathis, from which the river in Italy took its name; Bura and Helice , where the Ionians fled when they were worsted in battle by the Achaeans; Aegion; Rhype; Patrae ; Phareae; and Olenus , where is the great river Pirus; Dyme and Tritaeae, the only inland city of all these—these were the twelve divisions of the Ionians, as they are now of the Achaeans.
