Brosse, Salomon de (sälōmôNˈ də brôs) [key], 1571–1626, French architect, trained by his grandfather, Jacques du Cerceau, the elder. He paved the way for the next generation in the use of classicism as the style which denoted royalty. In Paris his works include the Luxembourg Palace (1615–20) built for Marie de' Medici and the facade of Saint-Gervais (1616). At Rennes he built the Parliament House (1618), now the Palais de Justice. Also by him are the châteaux of Blérancourt and Coulommiers.
