题目材料：
The archaeological evidence of the use of waterpower in Great Britain is even more substantial for Britain's Roman period than for the subsequent medieval period, when historians know that water mills were common. This kind of evidence casts doubt on the widely held theory that the introduction of powered milling (using waterpower to grind grain into flour) stimulated economic growth during the Middle Ages and encouraged a new attitude to the possibilities of exploiting the natural world. On the contrary, medieval people inherited a world in which water mills were already commonplace. And, furthermore, the excavated remains of Roman and medieval water mills prove that the design first described by the Roman engineer Vitruvius 2,000 years ago was scarcely modified until the eighteenth century. While a second type of water mill was introduced during the Middle Ages, it did not represent a technological advance, but was a simpler, less powerful mill that was cheaper to build than the more complex Vitruvian mill.
