Editorial note — The Germ:

{5} The sources from which these examples are drawn, and where many more might be found, are principally:—D'Agincourt: “Histoire de l'Art par les Monumens;”—Rossini: “Storia della Pittura;”—Ottley: “Italian School of Design,” and his 120 Fac-similes of scarce prints;—and the “Gates of San Giovanni,” by Ghiberti; of which last a cast of one entire is set up in the Central School of Design, Somerset House; portions of the same are also in the Royal Academy.
