Traité de geometrie
Sébastien Le Clerc's Traité de geometrie, printed in Paris by Jean Jombert in 1690, is a geometry textbook for students, engineers and draughtsmen, illustrated by the engraver himself. Its 191 woodcut and engraved figures are small line diagrams of triangles, polygons and projections, built from solid, dotted and dashed rules with letter labels, useful as ready-made technical line art, texture, and pattern fragments.
