Metalpoint is a traditional drawing technique in which a thin metal stylus, usually of silver, is used with paper that has been prepared with an abrasive coating traditionally made from powdered bone and gum-water. As the point is drawn along the surface, tiny traces of metal are left behind creating a delicate and very precise line. The medium was revived by artists in England during the second half of the nineteenth century. Strang was trained in the use of this highly disciplined drawing medium, by his teacher Alphons Legros, who was one of the chief exponents of this resurgence.
