Personifications
Like the Arch for Septimius Severus, this arch contains personified victories and seasons in the spandrels of the central archway and personified rivers in those of the lateral archways. The victories in particular offer a place to consider the changes in artistic style over time. In comparison to those on the nearby Arch for Titus, the winged victories from the era of Constantine are slightly more abstract in the spandrels, but still life-like in the way that the drapery flows around their bodies. But the style varies even within the Constantinian sculptures. The victory that flies above the armies in the encircling frieze exhibits far less detail. This discrepancy in style, due in part, to the extensive use of spoilia is what makes the Arch for Constantine so unique.
