horizontal wheel and vertical shaft are sometimes called "Greek Mills." A "Roman Mill" refers to a watermill that uses a vertical wheel (on a horizontal shaft). Greek style mills are the older and simpler of the two designs, but they require high water velocity to work well. The Roman style mills are much more complicated in their component parts
