Heresy has been treated as a crime to be tried in and punished by the ordinary courts of the country, as in the cases of Servetus and Grotius.
When the trial of Servetus was in progress (1553), Calvin was anxious for Farel's presence, but he did not arrive till sentence had been passed.
He accompanied Servetus to the stake, vainly urging him to a recantation at the last moment.
Symphorien Champier (Champerius or Campegius) of Lyons (1472-1539), a contemporary of Rabelais, and the patron of Servetus, wrote with fantastic enthusiasm on the superiority of the Greek to the Arabian physicians, and possibly did something to enlist in the same cause the two far greater men just mentioned.
Rabelais not only lectured on Galen and Hippocrates, but edited some works of the latter; and Michael Servetus (1511-1553), in a little tract Syruporum universa ratio, defended the practice of Galen as compared with that of the Arabians.
