We have seen that Mycenæan art was no exotic, transplanted full grown into Greece, but rather a native growth--influenced though it was by the earlier civilisations of the Cyclades and the East. This indigenous art, distinct and homogeneous in character, no matter whence came its germs and rudiments, must have been wrought out by a strong and gifted race. That it was of Hellenic stock we have assumed to be self-evident. But, as this premise is still in controversy, we have to inquire whether (aside from art) there are other considerations which make against the Hellenic origin of the Mycenæan peoples, and compel us to regard them as immigrants from the islands or the Orient. In the first place, recalling the results of our discussion of domestic and sepulchral architecture, we observe that neither in the Ægean nor in Syria do we find the gable-roof which prevails at Mycenæ. Nor would the people of these warm and dry climates have occasion to winter their herds in their own huts--an ancestral custom to which we have traced the origin of the avenues to the beehive tombs. Again, we have seen reason to refer the shaft-graves to a race or tribe other than that whose original dwelling we have recognised in the sunken hut. To this pit-burying stock we have assigned the upper-story habitations at Mycenæ. If we are right, now, in explaining this type of dwelling as a reminiscence of the pile-hut, it would follow that this stock, too, was of northern origin. The lake-dwelling habit, we know, prevailed throughout Northern Europe, an instance occurring, as we have seen, even in the Illyrian peninsula; while we have no reason to look for its origin to the Orient or the Ægean. It is indeed true that the island-folk were no strangers to the pile-dwelling, but this rather goes to show that they were colonists from the mainland. But, apart from the evidence of the upper-story abodes, are there other indications of an element among the Mycenæan people which had once actually dwelt in lakes or marshes? Monuments like the stone models from Melos and Amorgos have not indeed been found in the Peloponnesus, or on the mainland, but in default of such indirect testimony we have the immediate witness of actual settlements. Of the four most famous cities of the age, Mycenæ, Tiryns, Orchomenos, and Amyclæ, it is a singular fact that but one has a mountain-site, while the other three were once surrounded by marshes. The rock on which Tiryns is built, though it rises to a maximum elevation of some sixty feet above the plain, yet sinks so low on the north that the lower citadel is only a few feet above the level of the sea. Now this plain, as Aristotle asserts, and as the nature of the ground still bears witness, was originally an extensive morass. The founders, therefore, must have chosen this rock for their settlement, not because it was a stronghold in itself, but because it was protected by the swamp out of which it rose.
