Annunciation
Annunciation, the announcing to the Virgin Mary that she was about to be the mother of Christ. The 25th of March (also known as Lady-day) is the day on which the churches celebrate the Annunciation. The Annunciation has formed the subject of some of the very finest paintings in Christian art, and indeed was so frequently chosen as a theme that an annunciation now frequently means a picture whose subject is the Annunciation.
