Biography of Miguel Servet

Miguel Servet was born in Villanueva de Sigena , on September 29, 1511 . His father, Anton Servetus, was a royal notary who studied Latin, Hebrew and Greek. He studied law in Toulouse and later in one of his trips he met Juan Ecolampadio, who was the head of the reform in the city. He was in contact with Anabaptists , heretics who were persecuted and sentenced to death for not wanting to baptize their children and for defending baptism in adults, people who defended egalitarianism and pacifism .

His friendship with Ecolampadio ended in enmity and he was denounced before the municipal council for which he had to flee to Strasbourg where he meets Martín Bucero from whom he must also flee, which is why he moved to Paris where he used a false identity, Michel of Villeneuve . In Paris he was professor of mathematics , astronomy and astrology and in 1534 he met Juan Calvin , who would execute him years later.


Some time after meeting Calvin, Servetus wrote the book ” Institution of the Christian Religion “, a thesis in which he made great criticisms against Calvin . He wanted to meet with Calvino and see him, but he threatened to kill him. Some time later, the French Inquisition manages to enter the Spanish house in Vienna and stops him, but Miguel Servetus does not confess his true identity and plans an escape . On April 6, he managed to jump out of a window and escape. Despite this he was arrested and tried , he was also sentenced to pay a fine of 1,000 pounds of gold and wassentenced to death at the stake over low heat. The 27 of October of 1533 the court sentenced him to be tied up and taken to the hill of Champel where it would be burned with their manuscripts and books .

Miguel Servet managed to discover that blood reached the heart from different parts of the body , and that this blood could also transport carbon dioxide , that the heart drove the blood to the lungs where there was an exchange of gases and then returned to the heart where it was pumped to the rest of the body .
