This painting in the Tomb of Nakht (TT52), shows several men winnowing grain. Winnowing is the process of getting rid of the chaff, or inedible, part of the grain. Ancient Egyptian civilization, like all civilizations, was dependent on sophisticated agricultural techniques like winnowing. Using irrigation, winnowing, and crop rotation, civilizations allowed fewer farmers to produce more food.
