Display caption

This unfinished diagram is based on an illustration from Thomas Malton’s
A Compleat Treatise on Perspective 1775, which demonstrated ‘how to find the perspective representation of a triangle, having the original line given, in any plane, whose intersection and vanishing line is also given, and the place of the eye’.
