In the Via del Portico d'Ottavia at Rome, close by the Theatre of Marcellus, there still stands the propylaeum of the Porticus Octaviae, from which the street took its name. The inscription on the architrave records the restoration of the building by Septimus Severus and Caracalla in A.D. 203, but passes over in silence the previous history of the site. For that we are dependent largely on literary sources, chief among which is a passage of Velleius Paterculus, in which he records the building-activities of Q. Caecilius Metellus Macedonicus (cos. 143, censor 131 B.C.), the conqueror of Andriscus: Hic est Metellus Macedonicus, qui porticus, quae fuerunt circumdatae duabus aedibus sine inscriptione positis, quae nunc Octaviae porticibus ambiuntur, fecerat, quique hanc turmam statuarum equestrium quae frontem aedium spectant, hodieque maximum ornamentum eius loci, ex Macedonia detulit. … Hic idem primus omnium Romae aedem ex marmore in iis ipsis monumentis molitus <huius> vel magnificentiae vel luxuriae princeps fuit.
Velleius' statement, that the site of the Porticus Octaviae had formerly been occupied by a Porticus erected by Metellus, is clear, and adequately confirmed elsewhere. Less clear is what he says about the two temples, which we know from other evidence to have been dedicated to Juppiter Stator and Juno Regina.
