Marco d'Oggiono (c. 1470 – c. 1549) was an Italian Renaissance painter and a chief pupil of Leonardo da Vinci, many of whose works he copied.
Little is known of his life — not even the date of his important series of frescoes painted for the church of Santa Maria della Pace in Milan.
The Hungarian art critic Paul George Konody, in examining the Isleworth Mona Lisa, wrote of that painting: The hands, with their careful and somewhat hard drawing and terra cotta coloring, suggest at once the name of Leonardo's pupil, Marco d' Oggionno; whereas the inimitably soft and lovely painting of the head and bust, the exquisite subtlety of the expression, the golden glow of the general coloring, can be due only to Leonardo".
[1] Other works by d'Oggiono can be seen at Berlin, Paris, St. Petersburg and Turin, the one in Russia being a clever copy of the Last Supper by Leonardo.
[1] The Catholic Encyclopedia said of d'Oggiono, "[h]e cannot be regarded as an important artist, or even a very good copyist, but in his pictures the sky and mountains and the distant landscapes are always worthy of consideration, and in these we probably get the painter's best original work".
