"The Tidings Brought to Mary" refers to the moment when the angel Gabriel announced to Mary that she would conceive the Son of God, Jesus. This event is known as the Annunciation and is celebrated in Christian tradition. The angel conveyed that Mary would become the mother of the Messiah, despite being a virgin. Mary responded with humility and acceptance, expressing her willingness to fulfill God's plan. This moment is significant in Christianity as it marks the beginning of the Incarnation, where the divine takes on human form. The Annunciation is depicted in various works of art and is a key event in the Nativity story.
