Paul Cézanne has been called “the father of modern art,” a title that derives from Picasso, who once called him “the father of us all.” The most consequential Post-Impressionist of the 19th century, Cézanne’s radical explorations of dimension and color ushered in the modernist movements of the early 1900s. His legacy is palpable in two recently restored paintings at the Phillip’s Collection. Mont Sainte-Victoire (1886–87) and Self-Portrait (1878–80), though vastly different pieces in subject, hue, and emotion, both embody the versatility and genius that earned Cézanne his title as the patriarch of modern art. —Lucy Horowitz
