One of the most familiar traits of the part-horse, part-man creatures known as silens is their keen interest in women. In Athenian vase-painting, the female companions of the silens are characterized by a variety of attributes and items of dress, and exhibit mixed feelings toward the attentions of silens. The complexities of the imagery have resulted in disagreement in modern scholarship on several points, including the identity of these females, the significance of their attributes, and the explanation of a change in their receptivity to the advances of the silens. One of the reasons for the lack of consensus in the scholarship is the fact that the imagery raises not one question but many: questions concerning iconographical method, mythology, ritual, and poetry. In what follows I have attempted to separate some of these entangled issues. I hope to show that the companions of the silens are nymphs and not maenads, and that a major change in the iconography of silens and nymphs, occurring in late sixth-century red-figure Attic vase-painting, reflects in some way developments in the Athenian dramatic genre of satyr-play.
