The results of three excavations will especially serve as rallying points and supply a standard of comparison. After Schliemann’s death, Dörpfeld returned to Hissarlik, and recognised in the huge remains of the sixth stratum, on the southern skirts of the citadel mound, a city of the same period as Mycenæ at its acme. Thus we can study there remains of a later stage, in one process of development superposed on earlier remains, after an intervening period. The links there missing are, however, apparent at Phylakopi in Melos, excavated systematically from 1896 to 1899. Here buildings of three main periods appear one on another. The earliest overlie in one spot a deposit of sherds of the most primitive type known in the Ægean and found in the earliest cist-graves. The second and third cities rise one out of the other without evidence of long interval. A third and more important site than either, Knossos in Crete, awaits fuller publication. Here are ruins of a great palace, mainly of two periods. Originally constructed about 2000 B.C., it was almost entirely rebuilt at the acme of the Mycenæan Age, but substructures and other remains of the earlier palace underlie the later. Since recent researches, some of whose results are not yet published, have demonstrated that in certain localities, for instance, Cyprus, Crete, and most of the Ægean islands where Mycenæan remains were not long ago supposed to be merely sporadic, they form in fact a stratum to be expected on the site of almost every ancient Ægean settlement, we may safely assume that Mycenæan civilisation was a phase in the history of all the insular and peninsular territories of the east Mediterranean basin. Into the continents on the east and south we have no reason to suppose that its influence penetrated either very widely or very strongly. The remains that especially concern us here belong to the later period illustrated by these discoveries, and have everywhere a certain uniformity. Some common influence spread at a certain era over the Ægean area and reduced almost to identity a number of local civilisations of similar origin but diverse development. Surviving influences of these, however, combined with the constant geographical conditions to reintroduce some local differentiation into the Mycenæan products.
