The well-known ¿Berber Head¿ in the British Museum, found at Kyrene in 1861, has long defied exact stylistic analysis. Its findspot provides no precise date, and ever since the excavators suggested that it was a piece from the fourth century bc, this dating has been sustained, generally through inertia. Yet recent scholars have become increasingly aware of the weakness of this date without offering specific alternatives other than a gradual down-dating. Its North African features indicate that it is a portrait (...) of an indigenous ruler, and thus attribution must be based on the likelihood of such a person being honoured in Kyrene. It is herein suggested that it is a portrait of the Numidian prince Mastanabal, son of Massinissa, and that it dates to the time that Massinissa was a close associate of the king of Kyrene, the future Ptolemaios VIII of Egypt, or 163¿148 bc. Mastanabal was a noted athlete and thus the piece may be a commemoration of one of his victories. Its commissioning would fit into his father¿s vigorous hellenization policy. Although the style remains difficult of analysis, certain features, especially the beard under the chin, support a second-century bc date. (shrink)
