Diogenes seated with his barrel behind him, and reading a book while holding a stick that rests on a geometry book to his right. Artist: After Parmigianino (Girolamo Francesco Maria Mazzola) (Italian, Parma 1503-1540 Casalmaggiore); Giovanni Jacopo Caraglio (Italian, Parma or Verona ca. 1500/1505-1565 Krakow ()). Dimensions: Sheet: 11 1/4 × 8 9/16 in. (28.6 × 21.7 cm) trimmed within platemark. Date: 1524-27.This engraving of the Greek philosopher Diogenes follows a design by Parmigianino. In contrast to The Marriage of the Virgin it is striking how little of the copper plate Caraglio left unworked, using controlled tonal differences to achieve a highly nuanced chiaroscuro palette. This change may have been due to greater involvement by Parmigianino himself, who likely created his preparatory drawing with a print in mind. The painter actively thought about the translation of tonality in this design as is suggested by his decision to also have the drawing reproduced in a chiaroscuro wood
