palaces of Mycenæ and Tiryns. In Cnossos there was little or no fortification--another proof that the Minoan empire rested safe behind wooden walls. But on the mainland we have two magnificent fortresses and citadels, so well preserved and so cleverly excavated by Schliemann and Tsountas that the untrained eye can take in at a glance the essential features of the architecture. At Tiryns the builder has taken the fullest advantage of the natural strength of his position. The top of the hill has been levelled and the summit encircled with a gigantic wall seldom less than fifteen feet thick. In the wall there are galleries opening internally upon a series of magazines. Along it at intervals there are massive watch-towers. One such screens each of the gateways. The main gate on the east side is approached by a long ascending ramp, which is exposed all the way to attack from the wall that towers above. To reach the postern-gate on the west you had also to climb a long flight of steps. The hill-top, which is more than 900 feet long, consists of a lower plateau to the north, on which no traces of building have been found, possibly because there were only wooden erections there for the soldiers, or possibly because it was left bare as a place of refuge for the cattle. The higher plateau to the south contains the palace, with its great pillared megaron, or hall. In this there is a circular central hearth. Close behind is the hall of the women, with sleeping-chambers at hand, and a strong treasury partly built into the wall. There is an elaborate bathroom, with drain-pipes and water-supply, hot and cold, a little to the west of the megaron. The three inner courts are sumptuously paved with mosaic, and the walls were covered with frescoes. It appears that the buildings on the summit of the hill were all of a palatial description, and the conclusion is that the commons lived in the plain below, governed and protected by their citadel. Tiryns lies on the flank of the plain of Argos, and within a few miles of the sea. As this one small plain included also the other ancient fortresses of Mycenæ and Argos, the dominions of this king must have been very small. It has been plausibly suggested that these citadels principally existed to command the highways leading to the Isthmus of Corinth. At Mycenæ the fortification work is similar. Our view of the Lion Gate[8] will give some idea of the massive, Cyclopean masonry. The great relief itself is clearly a heraldic device; some such grouping of animals is constantly seen upon seals and gems, and the lion (or lioness?) has always been a royal beast. But, heraldic though it be, this enormous group is far from lifeless conventionality. Some scholars believe that the pillar between the animals is a proof of the much-discussed pillar-worship of prehistoric Greece. [Illustration: Beehive Tomb: Section]
