Many centuries ago, our ancestors discovered the possibility of harnessing the power of the elements—which, while helpful and useful on the one hand, could also be a threat as untamed forces of nature—for various purposes, thus eliminating the need for human or animal muscle power. Mills like these are a good example of the human engineering skills of earlier generations: The heavy millstones used to grind grain or press oil, for example, could be powered by wind or—as in this case—water.
