1748 La Topografia di Roma di Gio Batta Nolli dalla maggiore in questa minor tavola dal medesimo ridotta
Plan of Rome, reduced from the large Nolli plan on numerous sheets, with various views below.
With dedication to Cardinal Alessandro Albani, index of places, titled and signed 'Piranesi e Nolli incisero'
Nolli's large plan was published in sheets 1748, and he collaborated with Piranesi on this small reduction that appeared in the same sequence, after the index. This is why it has the plate number 33 at top left and 34 at top right. The plan is by Nolli, the views around it by Piranesi.
