Lorenzo was a nephew of Pope Leo X. In April 1518 Albany attended the christening of the Dauphin Francis, Lorenzo held the child at the font as the Pope's representative. Leonardo da Vinci designed the decorations at Amboise for the ceremony. In July 1518 Albany and Lorenzo were at the Castle of Saint-Saturnin in Auvergne and made a contract dividing their wives' Auvergne heritage lands between them. In March 1519, Pope Leo X confirmed the ancient privileges of the Scottish crown noting that he acted on the supplication of Albany, his "dilecti filli", "beloved nephew.".
