Preparatory drawing for Capricho 4, Mummy´s Boy (G01931, G02092). Its colour and the fact that it did not cover the surface of the paper particularly well made red chalk unsuitable for dark scenes. This explains the considerable differences in these images between the preparatory drawing and the print, with the luminosity of the former giving way to the etched darkness of the latter. Goya’s modifications to the composition include the cart, which was replaced by a basket in the final print.
