The present bronzes relate to a pair in the National Gallery of Art in Washington (inv. nos. 1942.9.143 and 1942.9.144), which have been variously attributed to Jacopo Sansovino, Alessandro Vittoria, and an anonymous Venetian caster. Compositionally the models appear to be derived from Alessandro Vittoria's autograph Jupiter in the Kunsthistorisches Museum, Vienna, and a figure of Juno attributed to Vittoria's workshop by Planiscig (op. cit.). However the characteristic features of the present bronzes, with large eyes and dense curls, indicate a possible affinity with the Roccatagliata workshop.
