Winnowing Grain
The three Egyptian farm laborers shown here illustrate one of the final stages in grain production. They are winnowing the combination of grain kernels, chaff, and stalk fragments produced as the oxen tread the threshing floor. Winnowing uses wind to separate the kernels from the chaff. The wind blows the chaff away and the heavier kernels, as well as some other plant fragments, drop straight to the ground, ready for sifting.
