The Doni Tondo is a circular panel painting of The Holy Family painted by the great renaissance polymath Michelangelo Buonarroti. The picture is surrounded by a wood-gilt frame designed, but not carved, by the artist. It was commissioned by the Florentine businessman Agnolo Doni to commemorate his marriage to Maddalena Strozzi from the powerful Florentine family who rivaled the Medici in the early years of the fifteenth century. Why Agnolo commissioned a renowned sculptor to paint this picture, and why Michelangelo agreed to execute the work, remains a mystery. However Michelangelo, despite his limited experience of tempera painting, has created a masterpiece of composition, beauty and invention.
