Marco d'Oggiono (1470-1549) was an Italian Renaissance painter and a chief pupil of Leonardo da Vinci, many of whose works he copied.
He was born at Oggiono near Milan.
Of the details of his life, we know almost nothing - not even the date of his important series of frescoes painted for the church of Santa Maria della Pace in Milan. He probably died in Milan.
Luigi Lanzi gave 1530 as the date of his death, but various writers in Milan say it took place in 1540, and now the best accepted date is 1549.
