Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ All appear to be amazed at the manner in which the two cousins treat each other at an age so tender, the one evincing his reverence for the Saviour, the other affectionately caressing his companion. Every touch of the pencil in the heads, hands, and feet of this work has produced such effect that the parts seem rather to be of the living flesh than the mere colours of the painter, however able a master of his art. This most noble picture is now in the possession of the heirs of Domenico Canigiani, by whom it is held in all that esteem which is due to a work of Raphael of Urbino. ”
