The present herm bust is a copy of one discovered in situ in the porticus of the Temple of Isis in Pompeii. The inscription translates as: 'To Gaius Norbanus Sorex, player of second parts. The magistri of the Pagus Augustus Felix Suburbanus, by decree of the decurions, set it up here.' Gaius Norbanus Sorex, an actor, is likely to also have been a magistrate, given that his monument was erected by the magistri of the Pagus Augustus Felix Suburbanus, a wealthy district of Pompeii. The monument was one of two in Pompeii commemorating Norbanus, suggesting that he was a man of considerable influence in the ancient town. Describing the herm, Katherine Welch has note that 'Sorex's portrait is rendered in a matter-of-fact, realistic-looking style. His face is irregularly shaped, his jaw is quite prominent and his underchin sags in the manner of many Roman republican period portraits. Yet the upward tilt of the head is an element one sees often in Hellenistic Greek portraits. It may be that this refinement was deemed appropriate to the representation of an actor' (K. E. Welch, 'Pompeian men and women in portrait sculpture', in P. Foss and J. J. Dobbins, The World of Pompeii, London, 2008, p. 565).
