Venus Callipyge

The Venus Callipyge, also known as the Aphrodite Kallipygos (Greek: Ἀφροδίτη Καλλίπυγος) or the Callipygian Venus, all literally meaning "Venus (or Aphrodite) of the beautiful buttocks", is an Ancient Roman marble statue, thought to be a copy of an older Greek original. In an example of anasyrma, it depicts a partially draped woman, raising her light peplos to uncover her hips and buttocks, and looking back and down over her shoulder, perhaps to evaluate them. The subject is conventionally identified as Venus (Aphrodite), though it may equally be a portrait of a mortal woman.
