The 17-day period beginning on Septuagesima Sunday was intended to be observed as a preparation for the season of
Lent, which is itself a period of spiritual preparation (for
Easter). In many countries, however, Septuagesima Sunday marked and still marks the traditional start of the
carnival season, culminating on
Shrove Tuesday, sometimes known as
Mardi Gras. In the pre-1970
Roman Rite liturgy, the
Alleluia ceases to be said during the liturgy. At first Vespers of Septuagesima Sunday, two alleluias are added to the closing verse of
Benedicamus Domino and its response,
Deo gratias, as during the
Easter Octave, and, starting at Compline, it is no longer used until Easter. Likewise, violet
vestments are worn, except on feasts, from Septuagesima Sunday until Holy Thursday. As during Advent and Lent, the
Gloria and
Te Deum are no longer said on Sundays. The readings at Matins for this week are the first few chapters of
Genesis, telling of the creation of the world, of
Adam and Eve, the fall of man and resulting expulsion from the
Garden of Eden, and the story of
Cain and Abel. In the following weeks before and during Lent, the readings continue to Noah, Abraham, Isaac, Jacob, and Moses. The
Gospel reading for Septuagesima week is the
parable of the Workers in the Vineyard (Matthew 20:1-16). ==Catholic usage after 1969==
