This article revisits the origins of the Alexander Mosaic at Pompeii by focusing on the figure standing at Alexander's right hand. The starting point is Andreas Rumpf's suggestion that this “right-hand man” may be the patron of the original painting, who wished to advertise his own role in the represented battle. It is argued that Ptolemy I is perhaps the strongest candidate on historical grounds, and that interesting connections can be drawn between the mosaic and the historian Kleitarchos, who worked at the Ptolemaic court. Circumstantial support for a Ptolemaic connection is supplied by other finds from the House of the Faun, three of which are briefly re-examined.

本文通过关注站在亚历山大右手边的人物，重新审视了庞贝城亚历山大马赛克的起源。出发点是 Andreas Rumpf 的建议，即这个“得力助手”可能是原画的赞助人，他希望在所代表的战斗中宣传自己的角色。有人认为，从历史角度来看，托勒密一世可能是最有力的候选人，并且可以在马赛克和在托勒密宫廷工作的历史学家 Kleitarchos 之间建立有趣的联系。牧神之屋的其他发现提供了对托勒密联系的间接支持，其中三个被简单地重新检查。
