On 16 February 1553, Michael Servetus while in Vienne, France, was denounced as a heretic by Guillaume de Trie, a rich merchant who had taken refuge in Geneva, and who was a good friend of Calvin,[REF] in a letter sent to a cousin, Antoine Arneys, who was living in Lyon.
Meaning to flee to Italy, Servetus inexplicably stopped in Geneva, where Calvin and his Reformers had denounced him.
