LITHOSTROTON, among the Romans, was a pavement of Mosaic work, consisting of small pieces of cut marble of different kinds and colours. The lithostreta began to be used in the time of Sylla, who made one at Præneste in the temple of Fortune. At last they were used in private houses; and were brought to such perfection, that they exhibited most lively re-
presentations of nature, with all the exactness of the finest painting.
