The first leaf contains a description of the rule of marteloio for resolving the course, with the "circle and square", two tables and two other diagrams. The next eight leaves contain various navigation charts. The ninth leaf contains a circular world map measuring 25 cm in circumference.

And the final leaf contains the Ptolemaic world map on Ptolemy's first projection, with graduation. Bianco also collaborated with Fra Mauro on the Fra Mauro world map of 1459.
