Winter was thought of as the reign of the winter spirits; these needed to be driven out in order for the summer to return. Carnival can thus be regarded as a rite of passage from darkness to light, from winter to summer: a fertility celebration, the first spring festival of the new year.
Traditionally, a carnival feast was the last opportunity for common people to eat well, as there was typically a food shortage at the end of the winter as stores ran out. Until spring produce was available, people were limited to the minimum necessary meals during this period. On what nowadays is called vastenavond (the days before fasting), all the remaining winter stores of lard, butter, and meat which were left would be eaten, for these would otherwise soon start to rot and decay. The selected livestock had already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.
