Valgrisi's blocks are the first full page illustrations for Ariosto, and correspond to those in the 1556 edition with small variants. Ruscelli explains to the reader the application of the rules of perspective to the multiple scenes in the cuts which are in the instructive tradition of the Marcolini Dante, with the upper part of the block often becoming a map, offering a tour of the canto by hippogryph.
