520
No parallel to the peculiar shape of cat. 520 has so far been found. Despite the fact that its body is hexagonal, the lamp can nevertheless be related to square-bodied lamps of Bailey type I. The color of its clay and slip, the depth of its basin, the globules impressed on the shoulder and base, and the plain planta pedis all attest to the eastern place of manufacture or origin of this lamp, purchased in Anatolia (see Loeschcke type VIII. Introduction, before cat. 278). The ogival nozzle with shoulder-volutes differs from the nozzle of square-bodied lamps, another reason to present this shape individually. Lacking comparanda, it is difficult to propose a date, but taking into account the shape of the ring handle and of the nozzle with its shoulder-volutes, the last third of the first century A.D. is suggested.
