Basilica of Neptune, Rome (Dolphin Frieze)
Detail of Dolphins, a shell, and an upright trident from the frieze course of the entablature of the Basilica of Neptune, Rome.
Date: Hadrianic. (Hadrian r. 117-138 CE).
The motif is popular for public buildings in Rome of the late first century (and the maritime theme is not necessarily associated with the function of the structure, such as a bath building).
