The Annunciation (from Latin annuntiatio), also referred to as the Annunciation to the Blessed Virgin Mary, the Annunciation of Our Lady, or the Annunciation of the Lord, is the Christian celebration of the announcement by the Archangel Gabriel to the Blessed Virgin Mary, that she would conceive and bear a son through a virgin birth and become the mother of Jesus Christ, the Christian Messiah and Son of God, marking the Incarnation. Gabriel told Mary to name her son Jesus, meaning "YHWH is salvation".
According to Luke 1:26, the Annunciation occurred "in the sixth month" of Elizabeth's pregnancy with John the Baptist. Many Christians observe this event with the Feast of the Annunciation on 25 March, an approximation of the northern vernal equinox nine full months before Christmas, the ceremonial birthday of Jesus. The Annunciation is a key topic in Christian art in general, as well as in Marian art in the Catholic Church, having been especially prominent during the Middle Ages and Renaissance. A work of art depicting the Annunciation is sometimes itself called an Annunciation.
