"Should we not mention among our truly noble buildings...the Temple of Peace...buildings the most beautiful the world has ever seen?" Pliny, Natural History (XXXVI.102)
The third of the imperial fora, the Forum of Vespasian (Forum Vespasiani) or, more properly, the Templum Pacis after the Temple of Peace that dominated the complex, was vowed by Vespasian in AD 71 after the capture of Jerusalem and dedicated four years later (Dio, LXV.15.1). It commemorated both the end of the Jewish war and the civil strife that had followed the death of Nero in AD 68. The forum, itself, consisted of a large enclosed square surrounded by porticoes with columns of pink granite from Aswan, Egypt. Along the lateral walls were two small rectangular exedras. Across the principle façade, the colonnade was in line with six larger and more widely spaced columns that corresponded to those of the temple, itself. Flanking the temple and continuing the line of columns were two large halls, with rooms thought to house Greek and Latin libraries (Bibliotheca Pacis) containing, among others, the works of Galen and Lucius Aelius (Gellius, XVI.8.2).
Virtually nothing of the forum now remains except a preserved wall and one of the exedra.
