This is a lovely set of books. The binding is leather. The edge of the pages and the front and back covers are marbled. The books measure 8" x 5". Volume 1 has 284 pages. Volume 2 has 349 pages. Petrarcha was an Italian scholar, poet and one of the earliest Renaissance humanists The books are written in Italian. This set was published in Milano by the Dalla Societa Tipografica De' Classici Italiani in 1805. Both books are in very good condition. They display beautifully. I am sure for an Italian reader or collector, the books would be quite desirable.
