Thus under the Dorian influence three new states were founded in the south and east of the peninsula, namely Messenia, Laconia, and Argos, which differed greatly even at the outset, and early diverged upon separate lines.
ARCADIA
At the same time great changes were taking place on the remote west coast. The states north and south of the Alpheus with which Homer is acquainted, were overthrown and Ætolian families, who honoured Oxylus as their ancestor, founded new lordships on the territory of the Epeans and Pylæans. These foundations had no apparent connection with the marches of the Dorian armies, and it is only a legendary poem of later date which speaks of Oxylus as having stipulated for the western land as his share in reward for services rendered to the Dorians. This betrays that it was a subsequent invention, by the fact that the new settlements on the peninsula are represented in this and similar fables as a result of a great and carefully planned undertaking; a representation which stands in complete contradiction to the facts of history. And when it is further related that the Dorians were conducted by their crafty leader, not along the flat coast road but across country through Arcadia, so that they might not be roused to envy or tempted to break their compact altogether, by the sight of the tracts of land conceded to Oxylus; this is but a tale invented with the object of explaining the erection of a state in Elis independently of the Dorian immigration, and the grounds for it are to be sought in the circumstance that the whole west coast, from the straits by Rhium down to Navarino, is distinguished by easy tracts of level country, such as are scarcely found elsewhere in Greek territory.
The best cornland lies at the foot of the Erymanthus Mountains, a broad plain through which the Peneus flows and which is surrounded by vine-clad hills stretching towards the neighbouring groups of islands. At the spot where the Peneus issues from the Arcadian mountains and flows into the coast-plain there rises on the left bank a stately height which looks clear over land and island sea and on this account was called in the Middle Ages, Calascope, or Belvidere. This height was selected by the Ætolian immigrants as their chief citadel; it became the royal fortress of the Oxylidæ and their following, into whose hands fell the best estates.
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.

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.
