The medallion is part of a larger group of sculptures, depicting some of the deities of the Roman pantheon who made up the group of the "Twelve Gods" (Jupiter, Juno, Minerva, Mercury, Apollo, Diana, Venus, Mars, Vulcan, Vesta, Neptune, Ceres). The busts of Aquileia, made by craftsmen from Asia Minor, perhaps belonged to two distinct series, which also included the goddess Rome, Hercules and Attis or Mithras. The medallions were found in fragments outside their original context, presumably a large late antique building built in the western area of the Roman city.
