In French, Mardi Gras means “Fat Tuesday” and is celebrated the day after Shrove Monday and the day before Ash Wednesday as a last “fling” before the 40 days of self-denial of Lent which precede Easter. Lent is a word that comes from the Middle English word “lente” which means “springtime” — so named for the season of the year in which it usually occurs. While the practice of Lent is not mentioned in the Bible, it has been a tradition in the Christian world since the mid 4th century. It seems to parallel the 40 days of fasting in the wilderness that Jesus experienced following his baptism at the Jordan River.

Origin of Mardi Gras

Historically, Lenten fasting became mandatory, especially abstinence from eating meat. While recommended by St. Athanasius, bishop of Alexandria in his Festal Letter III to his flock in Egypt in 331 AD, by the Middle Ages Lent was enforced throughout Europe, especially the forbidding of meat during the final weeks before Easter.
