The first of these views which attributes the Mycenæan culture to the Dorians of the traditional migration, cannot stand the test of chronology. For tradition refers that migration to the end of the twelfth century B.C., whereas the Mycenæan people were established in the Argolid before the sixteenth, probably even before the twentieth century. While Beloch’s hypothesis is not beset with this chronological difficulty, it is otherwise quite untenable. For, as the excavations at Tiryns and Mycenæ abundantly prove, the Mycenæan civilisation perished in a great catastrophe. The palaces of both were destroyed by fire after being so thoroughly pillaged that scarcely a single bit of metal was left in the ruins. Further, they were never rebuilt; and the sumptuous halls of Mycenæ were succeeded by the shabby hovels of which we have spoken. The larger domes at Mycenæ, whose sites were known, were likewise plundered--in all probability by the same hands that fired the palace. This is evidenced by the pottery found in the hovels and before the doorways of two of the beehive tombs. A similar catastrophe appears to have cut short the career of this civilisation in the other centres where it had flourished. How are we to account for this sudden and final overthrow otherwise than by assuming a great historic crisis, which left these mighty cities with their magnificent palaces only heaps of smoking ruins? And what other crisis can this have been than the irruption of the Dorians? And their descent into the Peloponnesus is traditionally dated at the very time which other considerations have led us to fix as the lower limit of the Mycenæan Age. Had that migration never been recorded by the ancients nor attested by the state of the Peloponnesus in historic times, we should still be led to infer it from the facts now put in evidence by the archæologist’s spade.
