The art of carving stone is known to scholars of the Ancient Near East as 'glyptics'; the more appropriate term 'sphragistics' (from the Greek sphragís) has not become widely accepted. Given the large number of attested original seals, and their impressions or rolled impressions from all periods, and given the great variety of types determined by their functions, seals constitute one of the most important sources in the cultural history of the Ancient Near East.
