Charles Sumner,
The Best Portraits in Engraving
“ Much that belongs to the painter belongs also to the engraver, who must have the same knowledge of contours, the same power of expression, the same sense of beauty, and the same ability in drawing with sureness of sight as if, according to Michael Angelo, he had "a pair of compasses in his eyes." These qualities in a high degree make the artist, whether painter or engraver, naturally excelling in portraits. But choice portraits are less numerous in engraving than in painting, for the reason, that painting does not always find a successful translator. ”
