The computer has not been widely used for the study and analysis of Greek and Roman pottery. Recently at Stobi in Yugoslavian Macedondia a considerable quantity of pottery has been coded according to a system devised specifically for the rather complex situation presented by the wide-reaching market for ceramics in the Greek and Roman periods. The system and coding procedures, as well as the preliminary results of the analysis, are published here in the hope that they will serve as an aid to others working with similar material.
