Queen of Heaven is the title given to the Blessed Virgin Mary in the Christian, mainly Roman Catholic, religion.  She ascended into heaven as the mother of Jesus Christ, the King of the Hebrews and Heavenly King of the Universe.  Depictions in art of Mary as Queen of Heaven date from early times, one of the first being Roman from the 6th century.

 

The canticle, the Magnificat, also known as The Song of Mary, is one of the earliest known hymns of the Christian Church.  Its text is from the Gospel of Luke (1:46-55) and tells of the visitation of Mary to her cousin Elizabeth when Elizabeth was pregnant with John the Baptist.  The child moves within Elizabeth's womb and when Elizabeth praises Mary for her faith, Mary sings the Magnificat in response.  Mary sings of the dawning of a new, righteous age.
