"Hence," says Lanzi, "some foreigners bestowed upon him the title of the Magician of Italian painting, for in him were renewed those celebrated illusions of antiquity.

Often, in comparing the figures of Guido with those of Guercino, one would say that the former had been fed with roses, and the latter with flesh, as observed by one of the ancients."
