The Henry II style was the chief artistic movement of the sixteenth century in France, part of Northern Mannerism. It came immediately after the High Renaissance and was largely the product of Italian influences. Francis I and his daughter-in-law, Catherine de' Medici, had imported to France a number of Italian artists from Raphael's workshop or former assistants of Michelangelo, known as the School of Fontainebleau, where many were based. Frenchmen were trained in the Mannerist idiom. Besides the work of Italians in France, many Frenchman picked up Italianisms while studying art in Italy during the middle of the century. The Henry II style, though named after Henry II of France, in fact lasted from about 1530 until 1590 under five French monarchs, their queens, and their mistresses.
