Eaten and cultivated since prehistoric times, onions were mentioned in the first dynasty of ancient Egypt, circa 3200 B.C.E., and have appeared in tomb paintings, inscriptions and documents from that time on. Some paintings depict onions heaped onto banquet tables, both the robust bulb onions as well as green onions (scallions). Of all foods in the plant kingdom it seems that onions set the record for the most frequent appearance in ancient Egyptian art. They were the staple food of the common person along with bread and beer... not much has changed it seems.
Over many centuries the onion occupied an exalted position as a work of art as well as a food.
