Don Luis de Borbón [1727-1785] was the younger brother of Charles III, and a patron of Goya. Destined by his family for an ecclesiastic career, he was made cardinal-archbishop of Toledo shortly after his eighth birthday in 1735. In 1841 he became archbishop of Seville. However, his scandalous behavior forced him to renounce his ecclesiastical offices at the age of twenty-seven. In 1776 he married María Teresa Vallabriga y Rozcas, thirty-one years his junior, against the wishes of his family. Since the marriage violated the laws stipulating that the child of the King had to marry a person of high noble rank, Don Luis' family was not allowed to visit Madrid. To bring cultural life to their palace at Arenas de San Pedro (Avila), Don Luis invited various artists, including Goya, to live with them for extended periods. The Infante had two children, María Teresa de Borbón y Vallabriga and Luis María de Borbón. Goya's portrait of María Teresa de Borbón y Vallabriga, later Condesa de Chinchón, is now in the NGA (1970.17.123).
