This work is the result of the analysis of some marble fragments, both architectural and sculptural, having different dimensions and found during the archaeological excavations in the area of the Circus Maximus. These fragments are partly unpublished and the new analysis brought about a new hypothesis of reconstruction of the architectural and decorative aspect of the Arch of Titus, which stood in the area of finding. In fact, it has been possible to calculate the height of the monument (20 m ca.), its width (17 m), and its depth (15 m). In addition, on the base of the recognisable fragments, we can say that the Arch was richly decorated: four fluted column shafts with Corinthian capitals and a smooth entablature were on its façades, as well as some panels and figured frizes, which were set upon the minor fornices, on the pillars, and between the architrave and the cornice. Finally, a bronze quadriga on the attic completed the complex decoration. In conclusion, this analysis confirms the attribution of the Arch to Domitian, the last emperor of the Flavian dynasty.
