INVESTIGATIONS AT ASSOS, 1881, 79

The volcanic crater of Assos formed a majestic natural altar
peculiarly adapted for a Greek acropolis. The irregular cone
is divided, as by a terrace, into two steps, which are in plan
so eccentrically related that their fortification walls are united
upon the east. The area of the inner enclosure contains very
nearly 3,cxDO square metres. The summit, which is not a perfect
plane, rises to the highest point at the extreme northwestern
corner. (See Plate 2). The altitude was determined, in the
lack of a level, by repeated barometrical readings to be 234
metres above the sea.
