A 1640 Paris treatise on incommensurable quantities by Jacques-Alexandre Le Tenneur, printed by I. Dedin and sold by Louys Boulanger and Augustin Courbé, aimed at French readers of mathematics and Euclid's tenth book. Its pictures are plain lettered geometric diagrams of rectangles divided into sections, with corner letters such as E, F, G and M, P, R, drawn in simple black line on cream paper. A designer could take from them a spare, systematic way of labelling proofs with letters and dividing a rectangle into parts.
