On Sundays lacking the commemoration of a feast of Double rank, or of an Octave, a second and a third prayer was added to that of the Sunday. These were called "seasonal" (in Latin, pro diversitate temporum) prayers, not "commemorations". For instance, from Advent to 2 February, the first of these additional prayers was in honour of Saint Mary and the other was either that "Against the persecutors of the Church" or that "For the Pope". The former "commemorations" must not be confused with the present-day "Memorials", celebrations of saints at a level lower than that of Feast or Solemnity.
