[Matthias Flacius Illyricus, the younger, professor philosophiae et logicae aristotelis and professor of the practical medicine].

The aim of this paper is to offer some new information on the life and work of Matthias Flacius Illiricus the Younger, especially concerning his activity as a medical doctor and university professor. According to our present knowledge, he published 17 of his writings during his lifetime. Matthias Flacius the Younger was born on September 12, 1547 in Braunschweig. His mother Elisabeth had 11 more children with Matthias Flacius the Elder.When Flacius the Younger was 15 (in 1562), his father sent him to Strassburg to study philosophy. According to some scholars (Waltraut Wienke, 2001), Flacius the Younger arrived to Rostock in August 1572 and was granted the title of magister philosophiae on April 1, 1574. According to the sources, that very year he was enrolled at the Faculty of Medicine in Rostock. On April 27, 1579 he was mentioned as lecturing at the Faculty of Philosophy, where he became Philosophiae & Logicae Aristotelis doctor in 1580. It is interesting that only a year later on September 23, 1581, when he was 33 years old, he became Doctor Medicinae by defending a dissertation entitled "De cattarrho; ward darauf zum Dr Med prom". In 1592 he exchanged his position at the Philosophy Chair in Rostock for the medical one, becoming a professor of Practical Medicine. Matthias Flacius the Younger died on April 27, 1593, when he was 46 years old.
