Originally a vessel for the mixing of wine with water, the normal custom in antiquity. In the study of classical Greek vases, the term is usually applied to a fairly large vessel with deep round bowl and wide mouth, standing on a broad base. The classification is normally subdivided into four types: column crater, volute crater, calyx crater and bell crater, which take their names from the characteristic shape either of the handle or of the body of the vase.
