Linear perspective : complete in four parts, 2s. each
A perspective instruction manual published in London by Ackermann & Co. in 1800, aimed at students learning linear perspective drawing. The plates are numbered diagrams of architecture, streets, and simple solids built on receding orthogonal and vanishing-point construction lines. A designer could take from them the clean line-only treatment of space, with a horizon line, a few figures for scale, and a floor grid that shows depth.
