Athanasius Kircher (1602–1680) (sometimes erroneously spelled Kirchner) was a 17th century German Jesuit scholar who published around 40 works, most notably in the fields of oriental studies, geology, and medicine. Kircher has been compared to fellow Jesuit Roger Boscovich and to Leonardo da Vinci for his enormous range of interests, and has been honored with the title "master of a hundred arts".
