L'art de nauiguer
A 1569 navigation manual by Pedro de Medina, printed in Lyon by Guillaume Rouille, aimed at sailors and pilots learning the art of seafaring. Its pictures are plain geometric diagrams: a compass rose with a star point, parallel-line grids with diagonal lines, a sun and figure beside a circle, and a circle with labelled chords. A designer could take their clean line work, labelled lettering and simple radial compositions as references for schematic instructional graphics.
