A steel engraving depicting Augustus’ now lost painting of Cleopatra VII in encaustic, which was discovered at Emperor Hadrian’s Villa (near Tivoli, Italy) in 1818; she is seen here wearing the golden radiant crown and the knotted robe of Isis. [703 x 500]

The painting is dated 28 BC. Plutarch writes that after the death of Cleopatra, Augustus Caesar (Octavian) celebrated a triumph in Rome and had an image of her shown in the procession. If true, the painting matches Plutarch’s account.
