fed enough to survive until the coming spring would provide new food sources. Traditionally, the feast also was a time to indulge in sexual desires, which were supposed to be suppressed during the following period fasting. Before Lent began, all rich food and drink were consumed in what became a giant celebration that involved the whole community, and is thought to be the origin of Carnival. In many Christian sermons and texts, the example of a vessel is used to explain Christian doctrine: "the nave of the church of baptism", "the ship of Mary", etc. The writings show that processions with ship-like carts were held and lavish feasts were celebrated on the eve of Lent or the greeting of spring in the early Middle Ages. The Lenten period of the liturgical calendar, the six weeks directly before Easter, was historically marked by fasting, study, and other pious or penitential practices. During Lent, no parties or celebrations were held, and people refrained from eating rich foods, such as meat, dairy, fat, and sugar. The first three classes were often totally unavailable during this period because of late winter shortages. While Christian festivals such as Corpus Christi were Church-sanctioned celebrations, Carnival was also a manifestation of European folk culture.

It was a time for catechumens (those converting to Christianity) to prepare for baptism at Easter. Carnival in the Middle Ages took not just a few days, but almost the entire period between Christmas and the beginning of Lent. In those two months, Christian populations used their several holidays as an outlet for their daily frustrations. Many synods and councils attempted to set things "right". Caesarius of Arles (470–542) protested around 500 CE in his sermons against the pagan practices. Centuries later, his statements were adapted as the building blocks of the Indiculus superstitionum et paganiarum ("small index of superstitious and pagan practices"), which was drafted by the Synod of Leptines in 742. It condemned the Spurcalibus en februario. Pope Gregory the Great (590–604) decided that fasting would start on Ash Wednesday. The whole Carnival event was set before the fasting, to set a clear division between celebrations and penitence. He also dispatched missionaries to sanctify any excesses in popular Carnival customs.
