Tobias Cohn studied medicine at the University of Padua. He practiced at first in Poland but eventually became the physician to five Ottoman sultans. His encyclopedic Ma’aseh Toviyyah (Venice, 1707) discusses Jewish theology, astronomy, medicine, hygiene, pharmacology, botany, and cosmography. Cohn rejected heliocentricism on religious grounds.
