A Spanish physician and theological writer; born at Tudela in Navarre, 1511; died at the stake in Geneva, Oct. 27, 1553. He accompanied Charles V. to Germany, as physician to the emperor's confessor Quintana. His work "On the Errors about the Trinity" was published at Hagenau, 1531, and it was soon afterward ordered to be burnt by the authorities at Basel: the reformer Bucer denounced the writer as deserving of the extremest punishment. Servetus defended his views in another work, "Dialogues on the Trinity" (1532), and then went to France. At Lyons he published "The Restoration of Christianism" (1553), and to escape punishment fled to Geneva. There, at the instance of Calvin, he was arrested on the charge of denying God and Christ, and burned as a heretic.
