ANAMORPHOSES. Set of four anamorphoses, watercolor and ink on paper: - two religious anamorphoses including Saint John the Baptist. Various formats. 18th century (mirror missing, tears, wetness). - two anamorphoses titled on reverse "La mort" and "Lamore en demoiselle". An anamorphosis depicting the Crucifixion is included. The principle of anamorphosis, invented by Piero Della Francesca, consists in creating a work distorted by cylindrical glass, stretching the lines vertically and horizontally, until they become illegible to the viewer. Placed behind a cylindrical mirror, whose location is indicated on the board, it reveals itself to the observer. Without it, the viewer sees only inconsistent elements. Today, anamorphosis is used by contemporary artists such as JR and Felice Varini.
