Setting aside the Dorian claim as preposterous, we have nothing to do but follow the epic tradition. The Homeric poems consistently assume that prior to any Dorian occupation Argolis was inhabited by other peoples, and notably by Achæans whose position is so commanding that the whole body of Greeks before Troy usually go by their name. Their capital is Mycenæ, and their monarch Agamemnon, King of Men; although we find them also in Laconia under the rule of Menelaus. But the poet has other names, hardly less famous, applied now to the people of Argolis and now to the Greeks at large. One of these names (Ἀργεῖοι) is purely geographical, whether it be restricted to the narrow Argolid district or extended to the wider Argos, and has no special ethnological significance. But the other (Δαναοί) belonged to a people distinct from and, according to uniform tradition, more ancient than the Achæans. We find, then, two races in Argolis before the Dorian migration, each famous in song and story, and each so powerful that its name may stand for all the inhabitants of Greece. The Achæans occupy Mycenæ, that is to say, the northern mountain region of the district, while legend represents the Danaans as inseparably connected with Argos and the sea-board, and ascribes to them certain works of irrigation. [Illustration: GALLERY IN THE WALL AROUND THE CITADEL OF TIRYNS] Whatever interpretation be put upon the myth, it seems clear that Argos could not feed its great cities without artificial irrigation, and this it owed to Danaus and his fifty daughters, “who were condemned perpetually to pour water in a tub full of holes,”--that is to say, into irrigation ditches which the thirsty soil kept draining dry. Now our study of the Mycenæan remains has already constrained us to distinguish in the Argolid two strata of Mycenæan peoples, one of them originally dwelling on dry land in sunken huts, the other occupying pile settlements in lakes and swamps. And since tradition squares so remarkably with the facts in evidence, may we not venture to identify the marsh-folk with the Danaans and the landsmen with the Achæans? But Achæans and Dorians were not alone in shaping and sharing Mycenæan culture; they had their congeners in other regions. Foremost among these were the Minyan founders of Orchomenos. As lake-dwellers and hydraulic engineers they are assimilated to the Danaans, whose near kinsmen they may have been, as the primitive islanders, whose abode we have found copied in the stone vases, must have been related to them both. Tradition has, in fact, preserved an account of the colonisation of Thera by a people coming from Bœotia, although it is uncertain whether it refers to the original occupation or to a settlement subsequent to the great catastrophe.
