The most important military event in the reign of Vespasian was the capture of Jerusalem by his son Titus in A.D. 70. Jerusalem had held out when Vespasian himself had earlier subdued the rest of Judaea. The victory solidified Flavian power in Rome, and in A.D. 71 the victory of Titus was turned into a joint triumph for Vespasian and Titus. The triumph included a procession carrying the spoils taken from the Temple in Jerusalem, an event later recorded on reliefs on the Arch of Titus in Rome. The reverse of this aureus celebrates the return of Titus from Jerusalem with a depiction of Neptune, god of the sea, characterized in the coin's legend as the Returner. He holds his usual attributes, a trident and an acrostolium or bow ornament of a ship.
