The counterpart to the portrait of Jupiter Serapis is the depiction of Juno Regina Isis, the goddess usually represented on the left side and Jupiter on the right side. The eagle is the usual attribute of the god, who in other representations as Dolichenus is dressed in complete military dress and is usually standing over a bull and not a globe like in our ring. In the Roman religion, Jupiter was obviously identified with Jupiter Optimus Maximus, the king of the gods. A video of this lot is available to view at TimeLine Auctions website.
