Raffaels Disputa; eine kritische studie über ihren inhalt
A German art-historical study by Anton Groner, published in Strassburg in 1905, examining the content of Raphael's Disputa fresco for scholars of Renaissance painting. The two plates show the Disputa in the Vatican and a related Florentine altarpiece scene, both in black and white halftone with ornate arched frames that a designer could use for classical composition and figure grouping.
