Among those who painted devotional Madonnas during the Early Renaissance are Fra Angelico, Fra Filippo Lippi, Verrocchio and Davide Ghirlandaio. The custom was continued by Botticelli who produced a series of Madonnas over a period of twenty years for the Medici; Perugino, whose Madonnas and saints are known for their sweetness and Leonardo da Vinci, for whom a number of small attributed Madonnas such as the "Benois Madonna" have survived. Even Michelangelo who was primarily a sculptor, was persuaded to paint the "Doni Tondo", while for Raphael, they are among his most popular and numerous works.
