A popular figure in religious works of art, the archangel Gabriel is most famous for the Annunciation: telling the Virgin Mary that she would give birth to the Messiah. God's messenger is also known as the Islamic angel of truth, the archangel of emotions and dreams, and the angel of hope and childbirth.

Richard Webster's second book of the archangels series chronicles the appearances of Gabriel among Old Testament figures, Islam prophets, and modern philosophers and artists. Webster then offers an array of techniques for contacting the angel of Annunciation, who can help with inspiration, purification, fertility, childbirth, achieving a fresh start, seeing the future, interpreting dreams/visions, developing clairvoyance, and overcoming limitations, such as doubt and fear.
