Question: Within six years of the official criminalization of heresy by the Emperor, the first Christian heretic to be executed, Priscillian, was condemned in 386 by Roman secular officials for sorcery, and put to death with four or five followers. However, his accusers were excommunicated both by Ambrose of Milan and Pope Siricius, who opposed Priscillian's heresy, but "believed capital punishment to be inappropriate at best and usually unequivocally evil". For some years after the Reformation, Protestant churches were also known to execute those they considered heretics, including Catholics. The last known heretic executed by sentence of the Roman Catholic Church was Spanish schoolmaster Cayetano Ripoll in 1826. The number of people executed as heretics under the authority of the various "ecclesiastical authorities"[note 1] is not known.[note 2] One of the first examples of the word as translated from the Nag Hammadi's Apocalypse of Peter was" they will cleave to the name of a dead man thinking that they will become pure. But they will become greatly defiled and they will fall into the name of error and into the hands of an evil cunning man and a manifold dogma, and they will be ruled heretically".
Is there an answer to this question: Who was executed for heresey in the 18th century?

Answer: unanswerable
