The term STABAT MATER is a 13th-century Roman Catholic hymn to Mary. The title is derived from its first line, 'Stabat Mater Dolorosa, ' which translates to 'the sorrowful mother was standing.' The hymn is often used during the liturgy of the Catholic Church and is a popular part of the Easter season. It is also used in other Christian denominations, including the Anglican and Lutheran churches.
