Apparatus consisting of a viewing grid made up of a frame with a set of precisely placed wires stretched across or set into it, vertically and horizontally. It is used by artists to facilitate the transfer or enlargement of an image from an object or original to a copy. The reticle is set up between the subject and the artist who then draws, square by square, the image he sees through the grid on to a sheet of similarly squared-up paper. Glass, set in a frame and etched with lines, can also be used as a reticle.
See the Abbreviations for further details.
