The Porticus Octaviae was built ostensibly by Octavia, the sister of Augustus, but really by Augustus and dedicated in the name of Octavia at some time after 27 B.C. , in place of the Porticus Metelli around the temples of Jupiter Stator and Juno. The statement of Cassius Dio that it was built after 33 B.C. from the spoils of the war in Dalmatia, is due to confusion with the porticus Octavia. It was burned in 80 A.D. and restored, probably by Domitian, and again after a second fire in 203 by Severus and Caracalla. It was adorned with foreign marble, and contained many famous works of art. Besides the Temples (q.v.) there were within the enclosure a Bibliotheca rected by Octavia in memory of the youthful Marcellus, a curia Octaviae , and a schola or scholae. Whether these were different parts of one building, or entirely different structures, is uncertain. It was probably in the curia that the senate is recorded as meeting . The whole is referred to by Pliny as Octaviae opera.
