What is true of Tiryns holds for Orchomenos as well. The original site was down in the plain until the periodic inundations of the lake forced the inhabitants to rebuild on the slopes of Mount Acontion; and Orchomenos was not the only primitive settlement in this great marsh. Tradition tells us also of Athenæ, Eleusis, Arne, Midea—cities which had long perished, and were but dimly remembered in historic times. To one of these, or to some other whose name has not come down to us, belong the remarkable remains on the Island of Goulas or Gha, which is connected with the shore by an ancient mole. During the Greek Revolution this island-fort was the refuge of the neighbouring population who found greater security there than in the mountains.
It is usually held that, when these Copaïc cities were founded, the region was in the main drained and arable, whereas afterwards, the natural outlets being choked up, the imprisoned waters flooded the plain, turned it into a lake, and so overwhelmed the towns. But, obviously, this is reversing the order of events. To have transformed the lake into a plain and kept it such would have demanded the co-operation of populous communities in the construction of costly embankments and perpetual vigilance in keeping them intact. Where were such organised forces to be found at a time anterior to the foundation of the cities themselves? Is it not more reasonable to believe that the builders of these cities—instead of finding Copaïs an arable plain, and failing to provide against its inundation—were induced by the very fact of its being a lake to establish themselves in it upon natural islands like the rock of Goulas, on artificial elevations, or even in pile-settlements? It is possible, indeed, that on some unusual rise of the waters, towns were submerged, but it is quite as probable that without any such catastrophe the inhabitants finally abandoned these of their own accord to settle in higher, healthier, and more convenient regions.
The case of Amyclæ is no exception. The prehistoric as well as the historic site is probably to be identified with that of the present village of Mahmud Bey, some five miles south of Sparta. The ground is low and wet, and in early times was undoubtedly a marsh.
In the plain of Thessaly, again, we may trace the same early order. There, where tradition (backed by the conclusions of modern science) tells us that the inflowing waters used to form stagnant lakes, we find low artificial mounds strewn with primitive potsherds. On these mounds, Lolling holds, the people pitched their settlements to secure them against overflow.
The choice of these marshy or insulated sites is all the more singular from the environment. Around Lake Copaïs, about Tiryns and Amyclæ, as well as in Thessaly, rise mountains which are nature’s own fastnesses and which would seem to invite primitive man to their shelter. The preference for these lowland or island settlements then, can only be explained in the first instance by immemorial custom, and, secondly, by consequent inexperience in military architecture. Naturally, a lake-dwelling people will be backward in learning to build stone walls strong enough to keep off a hostile force. And in default of such skill, instead of settling on the mountain slopes, they would in their migrations choose sites affording the best natural fortifications akin to their ancient environment of marsh or lake—reinforcing this on occasion by a moat, an embankment, or a pile-platform.
That the people in question once actually followed this way of living is beyond a doubt. Amyclæ shows no trace of wall, and probably never had any beyond a mere earthwork. The Cyclopean wall of Tiryns, as it now stands, does not belong to the earliest settlement, nor is it of uniform date. Adler holds that the first fortress must have been built of wood and sun-dried bricks. This construction may possibly account for those remarkable galleries whose origin and function are not yet altogether clear. The mere utility of the chambers for storage—a purpose they did unquestionably serve—hardly answers to the enormous outlay involved in contriving them. May we not, then, recognise in them a reminiscence of the primitive palisade-earthwork? In the so-called Lower Citadel of Tiryns we find no such passages, possibly because its Cyclopean wall was built at a later date. Likewise no proper galleries have yet been found at Mycenæ, and it is highly improbable that any such ever existed there. What had long been taken for a gallery in the north wall proves to be nothing but a little chamber measuring less than seven by twelve feet. Obviously, then, the gallery was not an established thing in fortress-architecture, and this fact shows that it did not originate with the builders of stone walls, but came to them as a heritage from earlier times and a more primitive art.
In fact, we find in the terramare of Italy palisade and earthwork fortifications so constructed that they may be regarded as a first stage in the development which culminates in the Tiryns galleries. The construction of the wall at Casione near Parma is thus described:[4] “Piles arranged in two parallel rows are driven in the ground with an inward slant so as to meet at the top, and this Δ-shaped gallery is then covered with earth. Along the inside of this embankment is carried a continuous series of square pens, built of beams laid one upon another, filled with earth and brushwood, and finally covered with a close-packed layer of sand and pebbles. This arrangement not only strengthens the wall but provides a level platform for its defenders.” Thus the space between these palisades would closely resemble the “arched” corridors of Tiryns, while the square pens (if covered over without being filled up) would correspond to the chambers.
These facts strengthen the inferences to which we have been led by our study of the stone models and the upper-story dwellings. And they point to the region beyond Mount Olympus as the earlier seat of this lake-dwelling contingent of the Mycenæan people as well as of their kinsmen of the earth-huts. And we have other evidence that the Mycenæan cities, at least the four of chief importance, were founded by a people who were not dependent on the sea and in whose life the pursuits of the sea were originally of little moment. Mycenæ and Orchomenos are at a considerable remove from the coast, while Amyclæ is a whole day’s journey from the nearest salt-water. Tiryns alone lies close to the sea-board; and, indeed, the waves of the Argolic Gulf must have washed yet nearer when its walls were reared. But, obviously, it was not the nearness of the sea that drew the founders to this low rock. For it is a harbourless shore that neighbours it, while a little farther down lies the secure haven of Nauplia guarded by the impregnable height of Palamedes; and it is yet to be explained why the Tirynthians, if they were a sea-faring people, did not build their city there. Again, the principal entrance to Tiryns is not on the side towards the sea, but on the east or landward side. This goes to show that even when the Cyclopean wall was built, certainly long after the first settlement, the people must have been still devoted mainly to tilling the soil and tending flocks, occupations to which the fertile plain and marshy feeding grounds would invite them. So in historic times, also, the town appears to have lain to the east of the citadel, not between it and the sea.
Even if it be granted that these Mycenæan cities were settled by immigrants who came by sea, it does not follow that they were originally a sea-faring folk. The primitive Dorians were hardly a maritime people, yet Grote has shown that their conquest of the Peloponnesus was in part effected by means of a fleet which launched from the Malian Gulf; and their kinsmen, who settled in Melos, Thera, and Crete, in all probability, sailed straight from the same northern port.
