The short, curling hair, slightly furrowed brow, articulated upward-gazing eyes, pronounced cheekbones and cropped facial hair are typical of portraiture of this time. The third century saw a trend in veristic portraiture that was perhaps a reaction to the unstable political climate, with the rapid ascension and declines of various "soldier-emperors." According to D.E.E. Kleiner (pp. 381-382 in Roman Sculpture, 1992), private portraiture of this period, "shows their indebtedness to contemporary imperial portraiture, especially to their military iconography...even though they often revealed the personal predilections of the patron and sometimes his position in Roman society." For a similar unidentified private portrait, once thought to be Emperor Trebonianus Gallus, see no. 49 in F. Johansen, Roman Portraits III, Ny Carlsberg Glyptotek.
