By the middle of the 1680s the Sun King was losing much of his shine. Mazarin had taught him to work rigorously, and Louis maintained a punishing schedule throughout his life, shrugging off a series of minor illnesses and not listening to the advice of his physicians. Eventually a broken arm put an end to his vigorous horseback riding, and gout ended his long walks around Versailles. He was wheeled to the throne room or carried to his carriage. In 1683 his first wife died, and Louis secretly married his longtime mistress, Françoise d’Aubigné, Marquise de Maintenon. In 1711 he went through the tragedy of the death of his oldest son and the following year that of his oldest grandson. Therefore, the kings successor was his little five year old great grandson Louis Duke of Anjou, who became King Louis XV of France after the death of his great-grandfather in 1715.
