A treatise on the curvilinear perspective of nature and its applicability to art
A treatise by William Gawin Herdman, published in London by John Weale & Co. in 1853, setting out a theory of curvilinear perspective for artists and students of drawing. The pictures are geometric line diagrams of converging vanishing points, arcs and radiating construction lines, which a designer could use as a reference for curved or distorted spatial layouts.
