Vedute di Roma (Rome, [1747?-1788]), pl. 59 NOTES: Once a rectangular portico which enclosed two temples, first built in 146BC it was reconstructed by Augustus in honour of his sister Octavia ca. 23BC. From the 12th to the 19th centuries it was used as a fish market, hence the name of the attached church, Sant'Angelo in Pescheria.
