The duke openly flaunted his affairs at court, especially the one with his long term lover Lorraine, who maintained a rocky relationship with Henriette.
In January 1670, his wife prevailed upon the King to imprison the chevalier, first near Lyon, then in the Mediterranean island-fortress of the Château d'If, and finally he was banished to Rome.
As greedy as a vulture, this younger son of the French branch of the House of Lorraine had, by the end of the 1650s, hooked Monsieur like a harpooned whale.
The young prince loved him with a passion that worried Madame Henrietta and the court bishop, Cosnac, but it was plain to the King that, thanks to the attractive face and sharp mind of the good-looking chevalier, he would have his way with his brother.
[3]In 1682, Lorraine was exiled again, having been accused of seducing the young Count of Vermandois (son of Louis XIV and Louise de La Vallière) with his set (including the Prince of Conti) and began practicing le vice italien (the contemporary term for homosexuality).
At the end of his life, by 1701, Philippe de Lorraine had lost much of the furniture in his apartment at the Palais-Royal and in his country residence (filled with remains from the Palatinate), his four abbeys, and all the money he had obtained (more or less with permission) from the coffers of the State, by gambling and exploitation of his lovers; however, he did manage to reconcile with Elizabeth Charlotte.
