Fra Angelico, The Annunciation
Fresco, 90.6 x 126.4 in. (230 x 321 cm.)
Northern Corridor, upper floor
Convent of San Marco, Florence, Italy
The multicolored wings seem to be a feature of Fra Angelico's Annunciations, as of course is the sense of calm and repose.
This photograph does not include the two inscriptions at the very bottom. The first is Salve Mater pietatis et totius trinitatis nobile Triclinium, "Hail Mother of Piety and noble couch of the Trinity." This is a stanza from one of the hymns of Adam of St. Victor (died 1146) for the feast of the Nativity of the Blessed Virgin (Wrangham, II, 222). The second is virginis intacte cum veneris ante figuram pretereundo cave ne sileatur ave, "When you come before the figure of the intact virgin, as you pass by, take care that you do not fail to say 'Ave!'"
