The numerous machines planned by Leonardo during his life are his genius's biggest testimonies. From engineering to mechanics, from anatomy to hydraulic: Leonardo attends at all these fields thanks to his deep capacity of observation of the nature and its phenomena. It's really his acute observation and his continuos experimentation that make Leonardo a forerunner of the modern science. The historical context in which he lived was obviously one of the most propitious. During the florentine period, spent in the workshop of the Verrocchio, Leonardo had way of seeing in action cranes and machinery planned by the master and great architect Filippo Brunelleschi; these machinery were necessary to put the big sphere made of bronze on the top of the dome skylight of the Santa Maria del Fiore cathedral. The news introduced by Leonardo in machinery study is the theoretical base which was before lacking. If cranes, hoists and sluices were planned before in an empirical way according to the customs of the time, Leonardo questions himself on the causes and the princes who regulates the working of them. He studies the single gears and the transformation ways of the movement: therefore after improving the single pieces he can introduce important innovations on his machines.
