As well as the Nereids, there were sculptures of various other figures, including several that served as acroteria, crowning the angles and apex of the pediment. Each of the two main surviving acroteria involves a young man and a young woman, and they are variously interpreted as representing the rape of the daughters of Leukippos by the twins Castor and Pollux, or as the Nereid Thetis being carried off by Peleus, or as exploits of Herakles.
