At the age of ten Cézanne entered the Saint Joseph school in Aix. In 1852 Cézanne entered the Collège Bourbon in Aix (now Collège Mignet), where he became friends with Émile Zola, who was in a less advanced class, as well as Baptistin Baille—three friends who came to be known as "Les Trois Inséparables" (The Three Inseparables). He stayed there for six years, though in the last two years he was a day scholar. In 1857, he began attending the Free Municipal School of Drawing in Aix, where he studied drawing under Joseph Gibert, a Spanish monk. From 1858 to 1861, complying with his father's wishes, Cézanne attended the law school of the University of Aix, while also receiving drawing lessons.
