Stabat mater
In the 16th centry, the hymn was added to the Roman missal. The Council of Trent banned it, like most sequences. In the 18th century it was added to the Breviary of Roman Catholic mass. The Second Vactican Council abolished this form of mass, so it is only part of regular mass one day of the year. The current version can be found in the Roman Gradual, which dates of 1973.
