This article takes as a starting point remarks of Auguste Rodin describing his modeling of a figure as a multiplicity of its profiles, and goes on to detail several methods used in that period to create sculpture from mechanically traced profiles -- with emphasis on photosculpture devised by Willème. Willème used two distinct methods, but both required 24 to 50 photographs taken from a circumference around the model. The profiles from these photographs were either traced onto a material, such as wood, which could be cut into the individual shapes and assembled into a three-dimensional form; or the photographs were projected and incised, using a system of double pantographs, directiy into the clay. -- AATA
