Close-up view of “industrial-style” grain grinders. These are large "hour-glass-shaped" grinders that fit over a stationary cone. Grain was placed in the top of them, the top was turned, and the ground grain (flour) came out the bottom. The basalt rock, from which the grinder is made, is the dominant stone in the region of Capernaum.
