The present article deals mainly with the works of Johannes Raicus, the scientist in the field of medicine from the 17th century, focusing on his treatise Disputatio physicomedica votiva e„j ƒšrwa surgenti jam Dorpati novo collegio region, debated at the Gymnasiumof Tartu by Petrus Turdinus, the future student of theology at the University of Tartu.When comparing this disputation with the rest of the works by both Johannes Raicus and Petrus Turdinus – physician and theologian respectively – it becomes clear that the author of the given treatise is indeed Johannes Raicus. Disputatio physicomedica votiva ... reveals an original approach to the subject matter, i.e. the city of Tartu,being clearly distinct from the medical works written in Academia Gustaviana, the Swedish University of Tartu, especially in the respect of developing the ideas of Paracelsus and his followers. Thus it can be concluded that Disputatio physico-medica votiva ...by Johannes Raicus is a peculiar phenomenon amongst the 17th century scientific works in Tartu.
