At what epoch did Ægean civilisation reach its full development? It is little use to ask when it arose. A _terminus a quo_ in the Neolithic Age can be dated only less vaguely than a geological stratum. But it is known within fairly definite limits when it ceased to be a dominant civilisation. Nothing but derived products of sub-Mycenæan style falls within the full Iron Age in the Ægean. Bronze, among useful metals, accompanies almost alone the genuine Mycenæan objects, at Enkomi in Cyprus, as at Mycenæ. This fact supplies a _terminus ad quem_, to which a date may be assigned at least as precise as scholars assign to the Homeric lays. For these represent a civilisation spread over the same area and in process of transition from bronze to iron, and if they fall in the ninth century B.C., then the Mycenæan period proper ends a little earlier, at any rate in the West. It is possible, indeed probable, that in Asia Minor and Cyprus, where the descent of northern tribes about 1000 B.C., remembered by the Greeks as the “Dorian Invasion,” did not have any direct effect, the Mycenæan culture survived longer in something like purity, and passed by an uninterrupted process of development into the Hellenic; and even in Crete, where there was certainly a cataclysm, and in the Argolid, where art was temporarily eclipsed about the tenth century, earlier influence survived and came once more to the surface when peace was restored. Persistence of artistic influence under a new order, and differences in the artistic history of different districts widely sundered, have to be taken into account. The appearance, _e.g._, of late Mycenæan objects in Cyprus, does not necessarily falsify the received Mycenæan dates in mainland Greece.
