[Sidenote: The Roman king seems to have personated Jupiter and worn his costume.] In the first place, then, it would seem that the Roman king personated no less a deity than Jupiter himself. For down to imperial times victorious generals celebrating a triumph, and magistrates presiding at the games in the Circus, wore the costume of Jupiter, which was borrowed for the occasion from his great temple on the Capitol; and it has been held with a high degree of probability both by ancients and moderns that in so doing they copied the traditionary attire and insignia of the Roman kings.[552] They rode a chariot drawn by four laurel-crowned horses through the city, where every one else went on foot;[553] they wore purple robes embroidered or spangled with gold; in the right hand they bore a branch of laurel and in the left hand an ivory sceptre topped with an eagle; a wreath of laurel crowned their brows; their face was reddened with vermilion; and over their head a slave held a heavy crown of massy gold fashioned in the likeness of oak leaves.[554] In this attire the assimilation of the man to the god comes out above all in the eagle-topped sceptre, the oaken crown, and the reddened face. For the eagle was the bird of Jove, the oak was his sacred tree, and the face of his image standing in his four-horse chariot on the Capitol was in like manner regularly dyed red on festivals; indeed, so important was it deemed to keep the divine features properly rouged that one of the first duties of the censors was to contract for having this done.[555] The Greeks sometimes painted red the face or the whole body of the wine-god Dionysus.[556] These customs may have been a substitute for an older practice of feeding a god by smearing the face, and especially the lips, of his idol with the blood of a sacrificial victim. Many examples of such a practice might be adduced from the religion of barbarous peoples.[557] As the triumphal procession always ended in the temple of Jupiter on the Capitol, it was peculiarly appropriate that the head of the victor should be graced by a crown of oak leaves, for not only was every oak consecrated to Jupiter,[558] but the Capitoline temple of the god was said to have been built by Romulus beside a sacred oak, venerated by shepherds, to which the king attached the spoils won by him from the enemy’s general in battle.[559] We are expressly told that the oak crown was [Sidenote: The oak crown as an emblem of Jupiter and of the Roman emperors.] sacred to Capitoline Jupiter;[560] a passage of Ovid proves that it was regarded as the god’s special emblem. Writing in exile on the shores of the Black Sea, the poet sends the book which he has just composed to Rome to be published there; he personifies the volume and imagines it passing along the Sacred Way and up to the door of the emperor’s stately palace on the Palatine hill. Above the portal hung shining arms and a crown of oak leaves.
