Julius Caesar returns and the senate awards him a triumph. Prisoners in chains and coaches with booty contribute to the mile-long procession. King Orodes II is paraded in his own wagon fettered with golden chains. The recovered aquilae standards of Crassus' lost legions are paraded in front of Caesar's carriage. The population goes wild and the city reverberates with the cry "Io triumphe!" The popularity of Caesar is now at its highest. Some plebeienans shout the forbidden "Caesar rex!" (king Caesar) and are immediately arrested by tribunes. Caesar refuses the honor of being declared of divine origin, a son of Jupiter.
