A bronze statue of the Roman Emperor Augustus (r. 27 B.C.– A.D. 14) who is portrayed as the deity Jupiter (Greek: Zeus). Note that he is holding a "thunderbolt" in his left hand.
This was discovered in the "Augusteum" — also called the "Sacellum (chapel/temple) of the Augustales (priests in charge of Emperor Worship)" at Herculaneum.
Herculaneum was destroyed in A.D. 79 by the eruption of the volcano Vesuvius—and thus the statue dates prior to that time—say, mid-first century A.D.
The statue is on display in the Naples Archaeological Museum (Museo Archeologico Nazionale di Napoli), Italy.
