Clarke published a Latin version of the "Traité de physique" of Jacques Rohault (1617(?)-1672) with notes, which he finished before he was twenty-two. The system of Rohault was based on Cartesian principles, and was previously known only through the medium of a crude Latin version. Clarke's translation (1697) continued to be used as a text-book in the university till supplanted by the treatises of Newton. Four editions were issued, the last being that of 1718. It was translated into English in 1723 by his younger brother John, dean of Salisbury.
