The three Sundays preceding Ash Wednesday are called Septuagesima, Sexagesima, and Quinquagesima, which mean, respectively, the seventieth, sixtieth, and fiftieth day, that is, before Easter.  The are mere names to correspond with the name of Lent (Quadragesima in Latin: fortieth); obviously they do not actually correspond with the period they indicate.
Man, victim of the sin of Adam and of his own sins, is justly afflicted, groans and sorrows encompass him.
