Scitlptitred reliefs as seen on stele-heads (No. 42 h). (c.) Free-standing statuary, consisting of groups, single figures, bigas (two-horse chariots), or quadrigas (four- horse chariots) (page 94). Color was largely used on buildings, and many traces are left, as already mentioned (page 53). In many instances the stonework, as in the Temples at Psestum and in Sicily, brickwork, and in some instances marble, were covered with carefully-prepared cement to receive wall paintings or color decoration, which appears to have been almost universal, especially in buildings of the Doric order. This cement casing was also capable of a high polish, and Vitrnvius mentions that well-polished stucco would reflect like a mirror. 5, REFERENCE BOOKS. Anderson (W.J.) and Spiers (R.
