Clementine Masses, also called "Passion Masses," were approved by Pope Clement XII (1730-1740) in a prayer book entitled "Prayer with Promises" from Anton Schmid publishers.
They are 6 masses for repose of any soul living or dead. Like the Gregorian Masses, they are said 6 days in a row. (Gregorian masses are 30 days in a row, as we all know.)
