Apparently lacking one leaf between pages 180 and 183. The rest of the pagination irregularities are just numbering errors.

Bound in contemporary vellum, soiled and with restored losses to the corners. The manuscript itself is in excellent condition with just a few defective leaves (f. 6 with loss of text, pp. 225-40 with outer margin and lower outer corner irregularly snipped away, minimally affecting the edges of a few drawings.)

A fine, unpublished architectural manuscript with sections on mathematics, perspective, ballistics. Several prominent buildings are described and illustrated, including Rome’s Saint Peter’s Basilica, the Palazzo dei Conservatori and Palazzo dei Senatori on the Campidoglio, Sant’Agnese, and the Villa Pamphili. The text is profusely illustrated with very precise architectural drawings in ink and wash.

The author draws from the central authorities of Renaissance and Baroque architecture: Serlio, Vignola, Scamozzi, Andrea del Pozzo and some of his drawings are closely related to or derive from those authors’ published works, as well as the vedute of Falda. The architectural treatise is followed, in a different but apparently contemporary hand, by a treatise on harmonic proportions. (p. 245-268).

Contents: Comparative table of different units of measure used in various parts of Italy as well as England, France, etc. (unsigned 1st leaf, recto).
