Another feature of this west wing is a series of eighteen magazines or storerooms which contained quantities of clay documents and great stone jars. The latter are decorated with horizontal bands, connected by diagonal ones, like the straw work on a modern ginger jar. This design, wrought upon the stone surface of these colossal jars, is an interesting memento of one of the primitive methods of clay modelling. For, before the invention of the potter’s wheel, the method of shaping, almost universally adopted, was one of the three following: (1) _scooping_ out from a ball of clay; (2) or _coiling_, in which the clay was rolled out into thin ropes, which were coiled round and round upon one another and then smoothed over; (3) or the building up of the form upon a shape of _basket-work_ or _matting_. A large bathroom was discovered in the northwest corner of the quadrangle but the actual residential quarters seem to have occupied the east wing. There are the remains of a _Megaron_, or great hall of state, approached directly from the central court, near which were found painted reliefs, illustrating scenes of the bull-ring, with female as well as male toreadors. These and other reliefs, some of which also commemorated incidents of bull-fighting, were not carved upon the stone, as in the Egyptian temples, or executed in tiles, as in Assyrian or Persian temples, but applied to the wall with hard plaster. This method, known as _gesso_ work, was used later in Byzantine decoration and by the Italians of the Renaissance, for decorative details; by Pinturricchio, for example, in the Borgia apartments of the Vatican. It has been revived by modern mural decorators; John S. Sargent, for instance, employing it in some of his panels in the Boston Public Library. To the south of the great hall a staircase, of which three flights and traces of a fourth are still preserved, descended to a series of halls and private rooms. Attached to one of these, identified as the “Queen’s Megaron,” was a bathroom, decorated with frescoes of flying fish. The drainage system in this part of the palace includes a water-closet and is of a complete and modern kind. The character and features of this palace are repeated on a smaller scale in those discovered at Phæstus, Hagia Triada, and other spots in Crete, and resemble in the main those of Mycenæ and Tiryns.
