Genesis 41:5 - Ellicott's Commentary On The Whole Bible

Seven ears... upon one stalk. — The wheat cultivated in Egypt is called triticum compositum, because it produces several ears upon the same stalk. The statement of Herodotus (ii. 36), that the Egyptians regarded it as disgraceful to feed upon wheat or barley, is disproved by the paintings in the temples, especially in the district of Thebes, which show that it was the main crop there, and its cultivation held in high honour. Maspero, Hist. Ancienne, p. 9, says, “In spite of Herodotus, the usual food of the people was wheat and other cereals, which the soil of Egypt produces in abundance.”
