The square houses, with thick walls, broken only by occasional narrow unglazed windows, were exactly like those of the Biblical pictures. Inside, the floors were of hard-beaten clay, and there were neither tables nor chairs, only earthen benches covered with sheep-skins or gay striped blankets. Some of the finer houses enclosed open courts or plazas, in which were trees and shrubs. The cooking was done in the open air, or in round-topped earthen ovens, built outside the houses.
