This study presents some historical aspects of health sciences through the health education school book written in the 16^th century for Transylvanian Saxon pupils. Paulus Kyr, doctor of Brașov (Kronstadt), a town in the Carpathian Arch, sums up the medical knowledge of his time for his pupils in a booklet called Sanitatis Studium. The booklet did not reach international fame, but serves with curiosities in cultural and health science history about the lifestyle of his time, and, at the same time, reveals aspects of the Renaissance’s reception in Transylvania. Kyr’s work has not lost anything from its topicality first and foremost due to the fact that appropriate lifestyle is being perceived as the key to preserving good health. This study reconsiders Kyr’s recommendations from the health sciences’ perspective of our days.
