Michael Servetus (/sərˈviːtəs/; Spanish:Miguel Serveto), also known as Miguel Servet, Miguel Serveto, Revés, or Michel de Villeneuve (29 September 1509 or 1511 – 27 October 1553), was a Spanish theologian, physician, cartographer, and Renaissance humanist. He was the first European to correctly describe the function of pulmonary circulation, as discussed in Christianismi Restitutio (1553). He was a polymath versed in many sciences: mathematics, astronomy and meteorology, geography, human anatomy, medicine and pharmacology, as well as jurisprudence, translation, poetry and the scholarly study of the Bible in its original languages. He is renowned in the history of several of these fields, particularly medicine and theology. He participated in the Protestant Reformation, and later developed a nontrinitarian Christology. Condemned by Catholics and Protestants alike, he was arrested in Geneva and burnt at the stake as a heretic by order of the city's Protestant governing council.
