The chief interest of Franciscus Sylvius (1614-1672) was alchemy. He was one of the founders of the iatrochemical school which thought that all phenomena of life and disease were based on chemical action.
Franciscus Sylvius was considered a great teacher of his time and was among the first to introduce ward instruction. His name is linked eponymously to the Sylvian fissure, but his relationship to this structure is obscure. The aqueduct between the third and fourth ventricules has been previously attributed to both Jacobus and Franciscus Sylvius but it had been described long before by others.
Sylvius was an early supporter of Harvey's concept of the circulation of the blood, and in his disputation of 1634 he proposed that there should be a pulmonary circulation.
Sylvius noted that some tremors were always present but others appeared only with movement. He explored the concept of thermal and tactile senses, had an understanding of ductless glands and was one of the first to propose that the pancreas produced a juice, which together with saliva and a form of fermentation, aided digestion. He was the first to describe tubercles and the process of cavitation.
