From here the Ætolian state, under the territorial name of Elis spread southward over the whole low country, where on the banks of the Alpheus the Epeans and Pylæans had once fought out those petty feuds of which Nestor was so fond of telling. On the decay of that maritime kingdom of the Neleidæ which was attacked on the south by the Messenian Dorians and on the north by the Epeans, Ætolian tribes pressed forward from the interior of the island; these were the Minyans who being expelled from Taygetus took possession of the mountains which run farthest in the direction of the Sicilian Sea from Arcadia. Here they settled themselves in six fortified towns, united by a common worship of Poseidon; Macistus and Lapreus, were the most distinguished. Thus between the Alpheus and the Neda, in what was afterwards the so-called Triphylia, or “country of three tribes,” a new Minyan state was formed. Finally the nucleus of a new state was also planted in the valley of the Alpheus, where scattered families of Achæans under Agorius of Helice allied themselves with Ætolian houses, and founded the state of Pisa. [Sidenote: [_ca._ 1000 B.C.]] Thus on the western coast, partly through conquest by the northern tribes and partly by arrivals from other parts of the peninsula, three new states arose, namely Elis, Pisa, and Triphylia; and in this way the whole coast district of the Peloponnesus was gradually newly populated and partitioned out afresh. Only in the district in the heart of the peninsula, did the country remain undisturbed in its existing state. Arcadia was regarded by the ancients as a pre-eminently Pelasgian country, and here it was thought the autochthonic condition of the aboriginal inhabitants had been longest preserved and had suffered the least disturbance. Nevertheless the native legends themselves distinctly indicate that here also immigrations took place, interrupting the uniform condition of Pelasgian life, and occasioning a fusion of races, of different character and origin. Here too there is no mistaking the epoch at which, as in all other Greek states, the historical movement began.
