Some ancient and modern sources suggest a fairly standard processional order. First came the captive leaders, allies, and soldiers (and sometimes their families) usually walking in chains; some were destined for execution or further display. Their captured weapons, armour, gold, silver, statuary, and curious or exotic treasures were carted behind them, along with paintings, tableaux, and models depicting significant places and episodes of the war. Next in line, all on foot, came Rome's senators and magistrates, followed by the general's lictors in their red war-robes, their fasces wreathed in laurel, then the general in his four-horse chariot. A companion, or a public slave, might share the chariot with him or, in some cases, his youngest children. His officers and elder sons rode horseback nearby. His unarmed soldiers followed in togas and laurel crowns, chanting "io triumphe!" and singing ribald songs at their general's expense. Somewhere in the procession, two flawless white oxen were led for the sacrifice to Jupiter, garland-decked and with gilded horns. All this was done to the accompaniment of music, clouds of incense, and the strewing of flowers.
