fame throughout Europe during this part of his career. In 1618, Rubens embarked upon a printmaking enterprise by soliciting an unusual triple privilege (an early form of copyright) to protect his designs in France, the Southern Netherlands, and United Provinces. He enlisted Lucas Vorsterman to engrave a number of his notable religious and mythological paintings, to which Rubens appended personal and professional dedications to noteworthy individuals in the Southern Netherlands, United Provinces, England, France, and Spain. With the exception of a few etchings, Rubens left the printmaking to specialists, who included Lucas Vorsterman, Paulus Pontius and Willem Panneels. He recruited a number of engravers trained by Christoffel Jegher, whom he carefully schooled in the more vigorous style he wanted. Rubens also designed the last significant woodcuts before the 19th-century revival in the technique. Marie de' Medici Cycle and diplomatic missions (1621–1630) In 1621, the Queen Mother of France, Marie de' Medici, commissioned Rubens to paint two large allegorical cycles celebrating her life and the life of her late husband, Henry IV, for the Luxembourg Palace in Paris. The Marie de' Medici cycle (now in the Louvre) was installed in 1625, and although he began work on the second series it was never completed. Marie was exiled from France in 1630 by her son, Louis XIII, and died in 1642 in the same house in Cologne where Rubens had lived as a child. After the end of the Twelve Years' Truce in 1621, the Spanish Habsburg rulers entrusted Rubens with a number of diplomatic missions. While in Paris in 1622 to discuss the Marie de' Medici cycle, Rubens engaged in clandestine information gathering activities, which at the time was an important task of diplomats. He relied on his friendship with Nicolas-Claude Fabri de Peiresc to get information on political developments in France. Between 1627 and 1630, Rubens's diplomatic career was particularly active, and he moved between the courts of Spain and England in an attempt to bring peace between the Spanish Netherlands and the United Provinces. He also made several trips to the northern Netherlands as both an artist and a diplomat. At the courts he sometimes encountered the attitude that courtiers should not use their hands in any art or trade, but he was also received as a gentleman by many. Rubens was raised by Philip IV of Spain to the nobility in 1624 and knighted by Charles I of
