Gabriel: Frame Roundel (left)

This frame roundel depicting the angel Gabriel belongs to a complex altarpiece structure produced by the anonymous Master of Pratovecchio, a Florentine painter active around 1450 whose name derives from the polyptych to which this roundel belonged. The Gabriel roundel paired with an Annunciate Virgin roundel to form the Annunciation within the altarpiece's decorative frame, a common Italian convention placing the Annunciation in the upper register of the framing structure rather than in the main panels below. The National Gallery's holdings of Pratovecchio Altarpiece components allow modern viewers to partially reconstruct the original complex ensemble.

Tempera and gold leaf on panel. The circular format demanded compositional concentration — Gabriel is presented in bust or half-length within the roundel's arc. Gold leaf ground establishes heavenly context. The tight frame forces the painter to convey the angel's message through gesture and facial expression rather than spatial staging.
