Angel of the annunciation

Sano di Pietro painted this Angel of the Annunciation around 1450, during his decades-long dominance of the Sienese devotional painting market. As the most productive painter in fifteenth-century Siena, Sano supplied churches, convents, confraternities, and private patrons across the Sienese countryside with an enormous volume of altarpieces and devotional panels. The isolated angel—typically the left half of a diptych whose right panel shows the Virgin—captures the celestial messenger's characteristic combination of reverent approach and joyful announcement. Sano's style consciously maintained the Sienese Gothic tradition of Simone Martini and the Lorenzetti brothers rather than embracing Florentine Renaissance innovations, suiting the conservative devotional tastes of his clients.

The gold-ground panel and delicate tempera technique continue Sienese trecento traditions, with the angel rendered in the refined linear style and gentle pastel palette that characterized Sano's workshop production.
