Raphael's Madonna Gonzaga : technical proofs of the authenticity and history of the painting
A 1916 Boston technical study by John T. Glodt arguing for the authenticity and history of Raphael's Madonna Gonzaga, aimed at art historians and collectors. Its pictures are reproductions of Madonna and child compositions in pen-and-ink sketch and lithograph styles, plus a rotated plate of a Van Dyck family group, offering a designer studies of soft contour line, hatching, and the seated mother-and-infant pose.
