Birth of the Virgin; Stories of the life of the Virgin

This Birth of the Virgin from 1437 at the Palazzo Corboli Museum depicts Mary's nativity—a subject popular in Sienese painting for its combination of domestic intimacy and theological significance. The scene follows the conventions of birth narratives: the new mother Saint Anne resting in bed, attendants washing the infant, family members and neighbors gathered. The Virgin's birth was not scriptural but derived from the apocryphal Protoevangelium of James, reflecting the medieval church's elaboration of Mary's biography to match the dignity of her later role. Sano renders the Sienese domestic interior with characteristic attention to detail, grounding the sacred narrative in recognizable everyday life.

The birth chamber is rendered with careful attention to domestic detail within the refined Sienese style, the attendant women and newborn Virgin arranged in a composition that balances sacred narrative with naturalistic observation of everyday life.
