The Arch of Septimius Severus () at the northwestern end of the Roman Forum is a white marble triumphal arch dedicated in 203 A.D. to commemorate the Parthian victories of Emperor Septimius Severus and his two sons, Caracalla and Geta, in the two campaigns against the Parthians of 194-195 A.D. and 197–199 A.D. After the death of Septimius Severus, his sons Caracalla and Geta were initially joint emperors. Caracalla had Geta assassinated in 212 A.D.; Geta's memorials were destroyed and all images or mentions of him were removed from public buildings and monuments. Accordingly, Geta's image and inscriptions referring to him were removed from the arch. Description The arch was raised on a travertine base originally approached by steps from the Forum's ancient level. The central archway, spanned by a richly coffered semicircular vault, has lateral openings to each side archway, a feature copied in many Early Modern triumphal arches. The Arch is about 23 meters in height, 25 meters in width. The arch bears two sets of reliefs. The first set includes four large panels on each face of the attic and the second set consists of eight panels that are set into the inner face of the four archways. The three archways rest on piers, which are composite columns on pedestals. Winged Victories are carved in relief in the spandrels. A staircase in the south pier leads to the top of the monument. Previously, the top of the arch had statues of the emperor and his two sons in a four-horse chariot (quadriga), accompanied by soldiers. The master architect is unknown, but he worked with a skill level that allowed him to create the arch in a quick and traditional manner. Although traditional with the columns, piers, and cornices, the style in which the architect shows the effects of texture, and the prominent and versatile planes, show a hint of deviation from the classical style. According the scholar Richard Brilliant, the variety of styles shown on the arch signify that many different workshops and sculptors were involved. This was a way to have the commission completed quickly. Brilliant made this conclusion by identifying how the same models for the motifs have small differences throughout the reliefs. Even individual sections such as the panels, middle reliefs, and column pedestals have distinctive techniques or styles that must have come from separate artists. The differences in styles are not so drastic
