October 26, 1553- the council of the City of Geneva writes
‘Having a summary of the process against the prisoner, Michael Servetus, and the reports of the parties consulted before us, it is hereby resolved, and, in consideration of his great errors and blasphemies, decreed, that he be taken to Champel, and there burned alive; that this sentence be carried into effect on the morrow, and that his books be burned with him.’
The council had little choice, since Servetus had
… spoken of the Trinity as a three-headed monster, comparable to the hell-dog of the heathen poets.
You might get away with that kind of nasty talk these days, but in the 16th century you only said that sort of thing if you had a death wish. Servetus evidently did, since he decided he’d go to Geneva, of all places, to say them.
