Alberti Dureri Clarissimi pictoris et geometrae de symmetria partium in rectis formis humanorum corporum
Dürer's 1532 Nuremberg treatise on the proportions of the human body, printed by the widow of Dürer's estate and edited with Joachim Camerarius, for artists and geometers. The pictures are plain line drawings of nude male and female figures set within grid lines, bearing plumb lines, compass arcs and measurement marks, which a designer could use as a model of constructed figure proportion.
