He portrayed the entire French court, the French high nobility, royalty, high members of the church and the state, parliamentarians and architects, and other notable people. His portrait of the poet Vincent Voiture was created around 1649 as the frontispiece for Voiture's published "Works" (published posthumously in 1650). The portrait is highly unusual in that Champaigne later reworked it as a portrait of a religious figure, Saint Louis (King Louis IX), to enable Voiture's daughter to keep it with her when she entered a convent.
