Leonardo's fascination with machines probably began during his boyhood. Some of his earliest sketches clearly show how various machine parts worked. Many ancient machines were in common use in Leonardo's time, e.g. ,water wheels turned millstones to grind grain and Archimedes's screw lifted water from streams providing a ready supply for drinking and washing. Leonardo developed a unique new attitude about machines. He reasoned that by understanding how each separate machine part worked, he could modify them and combine them in different ways to improve existing machines or create inventions no one had ever seen before. Leonardo set out to write the first explanations of how machines work and how the elements of machines can be combined.
