One of the great architectural etchers, Piranesi is best known for his imaginary Carceri d'Invenzione (Invented Prisons), etched in the 1740's. He also documented the ruins of Italian architecture and antiquities in a number of series of etchings.
This etching is plate 82 from his famous Views of Rome and is from the rare first state. The "Vedute de Roma" was a series of 137 etchings done between 1729 and 1778.
"Vedute di Campo Vaccino" is from a goup of etchings within the "Views.." that are sometimes called the "Temples" series. This image is also known as "The Forum Romanum, with the Temple of Antoninus and Faustina in the Foreground L., the Temple of Castor and Pollux, Foreground, R. and the Colosseum in the Distance." There are eleven temples described in the text of the plate, beneath the image.
