Polittico di Sansepolcro (detail) 1444

This detail from the *Polittico di Sansepolcro* (1444), by the Sienese painter Il Sassetta (Stefano di Giovanni, c. 1392 - c. 1451), depicts a scene of the Annunciation. An angel appears to the Virgin Mary, who is asleep in a bed. The scene is set in a room, with an open doorway revealing a man praying in the distance. This detailed depiction of the Annunciation is characteristic of Sassetta's style, known for its vibrant colors, expressive figures, and meticulous attention to detail. Sassetta's work, including this panel, is considered a significant example of the Sienese School of painting, which flourished during the 14th and 15th centuries. The scene, full of rich symbolism, invites the viewer to contemplate the spiritual significance of the Annunciation.
