We have taken a provisional and approximate date for the meridian age of Mycenæan culture--namely, from the sixteenth to the twelfth century B.C. We have also assumed that the Island culture was already somewhat advanced as far back as the earlier centuries of the second millennium before our era. This latter datum is based immediately on geological calculations: M. Fouqué, namely, has computed a date _circa_ 2000 B.C. for the upheaval which buried Thera, and thus preserved for us the primitive monuments of Ægean civilisation. Whatever be the value of Fouqué’s combinations--and they have been vigorously, if not victoriously, assailed--we may reach a like result by another way round. The Island culture is demonstrably older than the Mycenæan--it must have attained the stage upon which we find it at Thera a century or two at least before the bloom-time came in Argolis. If, then, we can date that bloom-time, we can control within limits the geologists’ results. Here we call in the aid of Egyptology. In Greece we find datable Egyptian products in Mycenæan deposits, and conversely in datable Egyptian deposits we find Mycenæan products. To take the first Mycenæan finds in Egypt. In a tomb of 1100 B.C., or within fifty years of that either way, at Kahun, Flinders Petrie found along with some dozens of bodies, “a great quantity of pottery, Egyptian, Phœnician, Cypriote, and Ægean”--notably an Ægean vase with an ivy leaf and stalk on each side, which he regards as the beginning of natural design. Further, at Gurob and elsewhere, the same untiring explorer has traced the Mycenæan false-necked vase or _Bügelkanne_ through a series of dated stages, “a chain of examples in sequence showing that the earliest geometrical pottery of Mycenæ begins about 1400 B.C., and is succeeded by the beginning of natural designs about 1100 B.C.” But long before these actual Mycenæan products came to light in Egypt, Egyptian art had told its story of relations with the Ægean folk. On the tomb-frescoes of Thebes we see pictured in four groups the tributaries of Tehutimes III (about 1500 B.C.), bringing their gifts to that great conqueror; among them, as we are told by the hieroglyphic text that runs with the painting, are “the princes of the land of Keftu [or Kefa] (Phœnicia) and of the islands in the great sea.” And the tribute in their hands includes vases of distinct Mycenæan style. On the other hand, we find datable Egyptian products in Mycenæan deposits in Greece. From Mycenæ itself and from Ialysos in Rhodes we have scarabs bearing the cartouches of Amenhotep III and of his queen Thi; and fragments of Egyptian porcelain, also from Mycenæ, bear the cartouches of the same king, whose reign is dated to the latter half of the fifteenth century.
