"The relationship between sketch and sculpture is revealed as a surprisingly narrow, mutually defining phenomenon of artistic expression, whereby the drawing reveals the artist's authorship." Friedrich MeschedennFor this publication, Mexican artist Dami?n Ortega (*1967 in Mexico City) has put together a selection of drawings that he uses to plan his sculptures and their installation in space. These drawings and designs are gathered together under the title Supervivencia de la Idea (Survival of the Idea), suggesting that for Dami?n Ortega, the medium of drawing-in this case, particularly the designs for monumental scenarios-is as important as the realized works, if not more so. In these drawings, the work is made public, and at the same time an application is laid out for the copyright of an idea. Hence, this selection of drawings for projects from 1991 to 2007 not only offers a retrospective survey of the development and conception of previous projects
