A detail of the pulpit next to the papal altar in St Peter&amp;#8217;s basilica, Vatican City, depicting the Annunciation.
The feast of the Annunciation is celebrated today. Usually the date is March 25, but as this fell on the Monday of Holy Week the solemnity was postponed to today.
The feast commemorates&nbsp;the announcement by the archangel Gabriel to Mary that she was to become the mother of Jesus. It is often considered as the beginning of the Incarnation story.
