In Catholicism, the Regina Coeli ("Queen of Heaven") is one of the four seasonal antiphons of the Blessed Virgin Mary, specifically Eastertide, prescribed to be sung or recited in the Liturgy of the Hours after night prayer (compline or vespers), from Holy Saturday to the Saturday after Pentecost.
The author is unknown. Legend has it that St Gregory the Great heard angels chanting the first three lines one Easter morning in Rome, and was inspired to add the fourth. Another apparently unfounded theory ascribes authorship to Pope Gregory V.
