What are these images?

The first and third are close-ups of Richard Serra's Torqued Ellipses (Dia:Beacon), bronze sculptures partly inspired by contemporary dance. The second is a dancing figurine in bronze from the Mahdia Shipwreck off the eastern coast of Tunisia, and the last is a "Libyan head" on a herm from Carthage (both ca. 2nd c. BCE; Bardo Museum, Tunis).
