Marcantonio Raimondi - Saturnus en de nimf Philyra
Giulio Bonasone was an Italian painter and engraver born in Bologna. He possibly studied painting under Lorenzo Sabbatini, and painted a Purgatory for the church of San Stefano, but all his paintings have been lost. He is better known as an engraver and is believed to have trained with Marcantonio Raimondi.
Printmaking in woodcut and engraving came to Northern Italy within a few decades of their invention north of the Alps. Engraving probably came first to Florence in the 1440s, the goldsmith Maso Finiguerra (1426–64) used the technique. Italian engraving caught the very early Renaissance, 1460–1490. Print copying was a widely accepted practice, as well as copying of paintings viewed as images in their own right.
