The earliest influences from Greece came, as has been hinted, through colonies like Chalcidian Cumae, which were the chief agents in the Hellenisation of Etruria; but at Cervetri, at any rate, the prevailing influence was Corinthian, as testified by the remarkable series of Corinthian and quasi-Corinthian vases in the Campana collection at the Louvre. Later in the sixth century came the connection with Athens, the chief results of which are to be seen in the contents of the tombs of Vulci (Vol. I. p. 76). It extends from the time of the Peisistratidae (540-520 B.C.) down to about 450 B.C., being probably brought to an end by the Peloponnesian War and the destruction of the Athenian maritime supremacy; but isolated instances of importations occur down to the time of Alexander the Great, in the Panathenaic amphorae of which dated examples of 336 B.C. have been found at Cervetri (Vol. I. p. 390). In sketching this outline of Hellenic influence in Etruria we have overstepped the limits of chronological sequence, and must retrace our steps in order to deal first with the local products of the period from 650 B.C. onwards, and secondly with the effects of the Greek civilisation on the same. * * * * * =Polledrara ware.=—The Grotta d’ Iside or Polledrara tomb at Vulci has been dated, on the authority of a scarab of Psammetichos I. (656-611 B.C.) which it contained, towards the closing years of the seventh century. This dating has been generally accepted, and there seems no reason to doubt it, although the evidence of an isolated scarab is not always as trustworthy as appears at first sight. Besides local bronze work and objects of Egyptian or quasi-Egyptian character, it contained one vase of unique character which calls for special consideration.[2283]
