The figure of Cristoforo Zabata represents an example of restless operator of the book in Italy in the second half of the 16th century. A paper maker, bookseller, writer and publisher, his name is often remembered for being the first publisher of a Canto of Tasso's Jerusalem Delivered. Up to now his human and professional figure was known in a very rough way. The volume, in addition to providing solid information on the biographical story of the protagonist, reconstructs his bookseller and publisher activity divided between Genoa, Pavia and Venice, assigning 21 editions to him, including the poetic collections of contemporary authors of which a full incipitary is provided. As evidence of his activity as a writer, the dedicatory letters and poetic compositions he created are published. The volume reconstructs a further piece of the variegated mosaic represented by the crafts of the book in 16th century Italy.
