Opvscoli morali
Opvscoli morali is a 1568 Venetian printed edition of moral essays by Leon Battista Alberti, published by Francesco Franceschi of Siena and held by the Getty Research Institute. The pictures are small black-and-white woodcut diagrams of perspective and surveying, showing a figure sighting a tower, a grid receding to a vanishing point, and geometric construction lines a designer could adapt for technical line art.
