The following paper was for the most part written early in 1939 and embodies the results of studies in Greece during the preceding year. Professor A. J. B. Wace, who suggested the subject to me, and to whom I am continuously indebted for encouragement and criticism, has elsewhere pointed out (notably, in collaboration with Professor Carl Biegen, in an article in Klio, 1939, 131 ff.) the need for a systematic and regional study of L.H. III pottery. The term covers wares produced over a period of at least three centuries (as long as from the reign of Charles I to the present day), and distributed over the Eastern Mediterranean from Sicily to Palestine. Within this wide range the existence of considerable variety has long been recognised, but not to any extent the nature of the variations, produced in part by the passage of time, in part by locally differing materials and traditions. This paper is an examination of what L.H. III pottery has come to light in one geographically well-defined region, Attica, and an attempt to discern the influences at work in its production, and its relation to similar pottery elsewhere.
