CAESAR - DIVI[•F] Venus Genetrix standing right, nude to below the hips, leaning with her left elbow on column to her left, holding crested helmet in her right hand and long transverse scepter in her left; to lower left, shield with star motif leaning against column.

As the mother of Aeneas, Venus was the mythical ancestress of the Julian family and hence venerated, in the form of Venus Genetrix, by both Julius Caesar and Octavian. The star on her shield is none other than the Sidus Iulium, a comet that appeared during the festivities held by Octavian in honor of Venus Genetrix on 20-23 July 44 BC, and was subsequently connected to Caesar's deification.
