Note (return) — Chapter I
Reading edition
In medicine Jews were pre-eminent in the Slavonic countries, as they were everywhere else. They were in great demand as court physicians, though several had to pay with their lives "for having failed to effect cures." Doctor Leo, who was at the court of Moscow in 1490, was mentioned above. Jacob Isaac, the "nobleman of Jerusalem" (Yerosalimska shlyakhta), was attached to the court of Sigismund, where he was held in high esteem. Prince Radziwill's physician was Itshe Nisanovich, and among those in attendance on John Sobieski were Jonas Casal and Abraham Troki, the latter the author of several works on medicine and natural philosophy.34
