 When he engraved after Parmigianino's "The Mystical Marriage of St. Catherine", he produced a composition that was very similar to the source except that he took away the window and elongated the entire work in order to lengthen the man in the lower right corner.By using big patches of white and dark, Bonasone highlights the linear beauty of the Virgin's hair and reflects the tonal beauty of Parmigianino's painting.It is challenging to evaluate the prints of Bonasone after Raphael's paintings due to the loss of many original paintings.
