Usually scholars have not paid much attention to the shaduf and they often described it without studying the historical developments of the mechanical principle on which its working is based. However, this water lifting device plays a very important role in the emergence of some basic concepts of mechanics: equilibrium and law of the lever. This paper trys to follow the history of these concepts in relation to the use of shaduf and pulley. It allows to identify a set of basic knowledge that we can find both in theoretical works (the oldest surviving text is the Pseudo-Aristotelian Mechanical Problems 300 BC) and in books more focused on practical applications.
