Salve Regina is one of the four Marian antiphons of the Catholic Church, traditionally attributed to the 11th century and sung at the end of Compline from Trinity Sunday until Advent. The text addresses Mary as queen and mother of mercy and is attributed in tradition to Hermann of Reichenau. Its simple chant melody has been preserved for centuries, later harmonised by many composers, and remains familiar from church services, recordings and film soundtracks evoking medieval devotion.
