The parts of an Anglo-Saxon mill

The literature on watermills is extensive, and includes many papers on what is usually called the ‘horizontal’ mill, that is to say mills with a horizontal wheel and a vertical shaft, as against those with a vertical wheel and a horizontal shaft. It is here proposed that the type under discussion in this paper, sometimes called the ‘Norse’ or ‘Greek’ mill, should be called the ‘horizontal-wheeled’ mill, and the other the ‘vertical-wheeled’ mill.
