Clements identified this study as of a circular altar, made of Pentelic marble in the Museo Capitolino, Rome. The foot and cornice are modern. It is decorated in relief with four clubs, connected with wreaths of oak and tied with ribbons. Figures or objects appear in the fields below, of which two are illustrated. A lengthy inscription declares that it was dedicated to Hercules Victor by C. Ulpius Fronto during the consulship of L. Vettius Paullo and T. Junius Montanus.
