Description: Andrea di Bartolo was influenced early in his career by the work of his father Bartolo di Fredi and of Paolo di Giovanni di Fei. Then he entered into the cultural climate of the late fourteenth century. The two panels, cut on each side, belonged to the upper section of a polyptych and represent the Announcing Angel, kneeling and holding a scroll, and the Virgin, kneeling with her hand on her chest. The two tablets were clearly influenced by Simone Martini, although the grace of the Virgin and some other stylistic and typological traits are recurring elements in the production of the artist. As for the dating of the piece, the most recent criticism states that the panels are related to the fragmentary altarpiece of Buonconvento, and perhaps closer in date to the work of 1397, in which Andrea di Bartolo set out to rival the previous generation of artists, including Paolo di Giovanni di Fei.
