Cereal crops belong to the Graminae (grasses) family, whose fruits are grain-shaped. They come from plants which used to grow freely. Humans adapted seven species: rice, wheat, oats, corn, rye, barley and millet, making them their basic foodstuff for centuries due to their exceptional nourishing qualities and easy preservation.
Over history, cereal crops have been linked to diverse beliefs and symbolisms, being considered as symbols of fecundity, wealth and abundance. They have been paid tribute by many cultures.
The word cereal derives from Ceres, goddess of agriculture and one of the main divinities in Roman mythology. In Greek mythology, Ceres is Demeter, goddess of grains and harvests.

Farming tasks connected to cereal cultivation and processing imply hard work, from seeding to harvesting. It is a long processing chain which ends in the making of bread and has remained unalterable over the centuries.

Agricultural activities have been very common in the region, and its teaching has passed from parents to children. Mechanization of farming tasks and new techniques have transformed them, manual tasks being replaced by threshers, winnowing machines and combines, which carry out the whole process from harvest to grain storage. They have meant a great innovation in the agricultural sector.
