Over the square-headed gate there was to be, for whatever reason, a triangular hole, doubtless meant to be filled with a stone of its own shape. In the treasuries either this stone was never put in or it is gone. In the lion-gate it was put in, as it seems to us, when art had passed the stage represented by the lion-gate itself, and had reached the stage which is represented by the gateways of the treasuries. Another thought suggests itself. At Mykênê, as less clearly at Tiryns, the lion-gate, with its skilfully guarded approach, does not lead at once into the higher enclosure of the akropolis, but into the outer and lower one. Does this go at all to show that this outer enclosure, at Mykênê at least, was an addition to the primitive fortress of all, fencing in the upper part of the hill? The fact that the tombs were found in the lower enclosure also looks this way. There must have been a time when this ground was looked upon as being outside the city, or it would hardly have been used for purposes of burial. The argument does not quite reach demonstration; burial within the walls was not absolutely unknown even in historical Greece, and it may not be safe to argue from historical to primæval Greece. Still the two arguments so far fall together as at least to suggest the idea that we have in the inner enclosure something yet more ancient and venerable than all--something which may have been ancient and venerable, not only in the days of Homer, but in the days of those whose tale Homer has told. For the present we keep within the akropolis, within the old hill fort which forms the inner circle of the Ekbatana of the imperial lords of præ-historic Hellas. We stand here within the walls which struck the minds of so many of the poets of Greece in the days when their desolation was a thing of yesterday--walls which seemed too mighty to be the work of mortal men, and which, like their fellows elsewhere, were deemed to have been wrought by the same hands which forged the thunderbolts of Zeus. Here we may in truth Φάσκειν Μυκήνας τὰς πολυχρύσους ὁρᾷν, πολύφθορόν τε δῶμα Πελοπιδῶν τόδε--
