Analytical institutions
Analytical Institutions, published in London by Taylor in 1801, is a mathematics textbook by Maria Gaetana Agnesi, written as an introduction to analytic geometry and calculus for students. Its pictures are plain lettered geometric diagrams with a labelled figure of curves, points and lines set on a pale page, and a designer might take from them a clean, precise schematic style for technical line work. Fig. 91 shows a curve rising from point A with labelled points B, P, G, O, D, M, Q, a construction that suggests simple annotated diagram layouts.
