The Pisatae were one of many such tribal groups, or amphictyonies in the Peloponnese, in parts of which this form of life continued into the fifth century or later. Such were the groups of nine cities mentioned in the catalogue of the ships in the _Iliad_, the nine Arcadian cities grouped round the tomb of Aepytus, the nine Pylian cities of Nestor’s kingdom, the nine Argive cities under Diomed, the nine Lacedaemonian cities under Sparta. Such, too, were the Caucones, a wandering tribe whose hero Caucon was in later times supposed to be buried near Lepreum; such were the Epeans of Elis; while the Eleans who supplanted them retained this form of government till the founding of the city-state of Elis in the fifth century. Like all such clans these leagues were intensely aristocratic: the chieftains were regarded with superstitious reverence, and the tribal centre was often the tomb of some departed hero-chief. Of cities, properly speaking, there were none in the western Peloponnese. A few strong fortresses served as residences for powerful chieftains and as refuge for their followers in danger; but most of the people lived in unwalled villages like the Scotch Highlanders. Their wealth consisted largely in horses and cattle, which they bartered with the islanders or with Cretan or Phoenician traders who landed at Pylos or sailed up the Alpheus to Olympia. In search of pasturage they ranged in winter over the lowland plains, retiring in summer to the sheltered upland valleys. The constant pressure of newcomers kept them constantly on the move, southwards and eastwards. This shifting of the tribal centres may be traced in the places that bore the name of Pylos. Settling originally in Elean Pylos, the gateway of the netherworld, these Pylians, united by some netherworld cult, were forced to move first to Triphylian Pylos, probably the Pylos of Nestor, and at a later stage to Messenian Pylos. Of their raids and cattle-lifting, their feuds and their reprisals, we have a vivid picture in the _Odyssey_. Such, we may suppose, was the life of the Pisatae and their neighbours, the pre-Dorian inhabitants of Elis, Triphylia, Arcadia and Messenia. The Pisatae perhaps enjoyed a position more established than the rest, thanks to the superstitious reverence which alone saved the rich valley of Olympia from attack, but under these unsettled conditions the real development of the festival was impossible, though the prestige which it had already acquired is shown in the building of the Heraeum by the Scilluntines.
