Gary Tinterow in "Recent Acquisitions, A Selection: 2007–2008." Metropolitan Museum of Art Bulletin 66 (Fall 2008), p. 37, ill (color), notes that it is one of only a few studies of a male nude by Degas and that it was painted over an earlier study of a nude that was oriented vertically; notes that a similar figure appears in "Scene of War in the Middle Ages" (1865; Musée D'Orsay, Paris) and that the pose also appears in pastels of female bathers in the 1880s and 1890s; compares it to a nude in the foreground of Ingres's "Romulus Victorious over Acron" (1812; Musée Augustin, Toulouse).
