(Σωσίβιος), an Athenian sculptor, known as the maker of a vase about two feet high, in the Louvre, adorned with eight figures in relief, of which two are those of Artemis and Hermes, and the remaining six represent a sacrifice. The two figures of divinities are in the archaic style, but the others display a freedom and grace, which has led Waagen to suppose it not improbable that the artist lived in the time of Pheidias. The architectural ornaments on the vase are quite in the style of that age. (Clarac, pl. 126, No. 332; Bouillon, 3.79; Waagen, Kunstwerke u. Künstler in Paris, p. 101; Nagler, Künstler-Lexicon, s. v. Sosibius.)
