It is thought that the Romans were the first to have started a milling industry using animals or teams of slaves to drive the wheels to grind the wheat. Before this, grinding of meal had mostly been carried out in the home using a device called a hand-quern. The hand-quern consisted of two round flat stones, one above the other.
