Jo. Archiepiscopi Cantuariensis Perspectiua communis
John Peckham's Perspectiva communis, a Latin optics treatise printed in Venice in 1504 by Giovanni Battista Sessa, edited by Luca Gaurico, and written for scholars and students of natural philosophy. Its pictures are geometric diagrams of circles, triangles, chords and rays, drawn with lettered points and plain line work, offering a designer clear models of compass-and-straightedge construction and a sense of early scientific notation.
