A special feature of the excavations at Collegium Jenense is the exceptionally good preservation of textiles in the tombs of the professors and their family members. Remains of the clothing in which they were buried have been preserved from over 30 people and almost all of the clothing from around 10 people. Using the example of the Jena physician Johann Arnold Friderici (1637-1672), who was also rector of the university in the winter semesters of 1664 and 1670, the preserved clothing will be presented and explained in comparison to his pictorial representations. In this context, attention will also be paid to Friderici's life and his study trip and how this influenced his style of dress.
