"After Schongauer of the German school, come Israel Von Mencken and A. Stockenden, the first represented by 'The Death of the Virgin' and 'Judith with the Head of Holofernes' -both very fine impressions - the second by 'Christ before Pilate' and 'La Des- cent aux Limbes.' In all of theses engravings, we see talent of a high order struggling with imperfect knowledge of what at the present day are considered the simplest artistic principles. The drawing is crude, and there is little knowledge of perspective or of light and shade." [P. 16-7b.]
