Euclidis elementorvm libri XV : unà cum scholijs antiquis
Euclid's Elementos, the Greek geometry text with ancient commentaries, printed in Pisaro in 1572 by Camillo Francischini for scholars and students of mathematics. Its pages are dense with text and geometric diagrams: circles with inscribed triangles, a pyramid with lettered vertices, and a polygon inside a circle, all drawn in fine black line with capital letter labels that a designer could borrow for minimal technical linework.
