Pliny testifies to a legendary 5th century B.C. contest between the sculptors Polykleitos, Phidias, Cresilas, Cydon and Phradmon to create an Amazon for the Temple of Artemis at Ephesos (Natural History, 34-53). There is much scholarly debate attempting to assign authorship to the surviving Amazon sculpture types. The "Sosikles" Amazon is usually attributed to Polykleitos, the winner of the contest, and is named for a version in the Museo Capitolino in Rome signed on the base by the Neo-Attic sculptor Sosikles. For the type and a full description of the contest and debate see no. 389, p. 262 in Stewart, Greek Sculpture.
