The inscription on the attic of the arch, on the side facing the valley of the Colosseum, is still legible today. It reads: "The Senate and the People of Rome to the God Titus, son of the divine Vespasian, Vespasianus Augustus".
The Arch was constructed after the death of Titus to celebrate the victory in 71 AD over the Jews and the destruction of Solomon's Temple. Two episodes of this triumph can be seen in the reliefs that decorate the internal walls.
In one of these, the procession of the Emperor is shown at the beginning of the ceremony as it goes through the Triumphal Gate; on parade are the trophies taken from the Temple of Jerusalem, including a candelabra with seven candlesticks, whose depiction here is the oldest on record. The other relief shows the goddess Roma, in a four-horse chariot, driving Titus as he is being crowned by Victory herself.
The vault of the arch is decorated with caissons and here Titus is being carried in the sky by an eagle, a clear symbol of the deification of the emperor.
