The Regina Caeli or Regina Coeli (“Queen of Heaven”), is an ancient Latin Marian Hymm of the Christian Church, is one of the four seasonal Marian Antiphons of the Blessed Virgin Mary, prescribed to be sung or recited in the Liturgy of the Hours at the conclusion of the last of the hours to be prayed in common that day, typically night prayer (Compline or Vespers).
The Regina Caeli is sung or recited in place of the Angelus during the Easter Season, from Holy Saturday through Pentecost Sunday.
While the authorship of the Regina Caeli is unknown, the hymn has been traced back to the twelfth century. It was in Franciscan use, after Compline, in the first half of the following century. Legend has it that St Gregory the Great heard angels chanting the first three lines one Easter Morning in Rome, while following barefoot in a great religious procession the icon of the Virgin painted by Luke the Evangelist. He was thereupon inspired to add the fourth line.
