About Jacques Gruet
Lived 1501 – 1547 (aged 45–46). Jacques Gruet was a politician.
Jacques Gruet (died July 26, 1547) was a notary put to death in Geneva for allegedly threatening John Calvin.
Family and life Jacques Gruet was the son of Humbert Gruet, a notary public of Geneva. Humbert died in 1513, and Gruet's mother died after 1522. He also had a sister, Hugonine, who died in 1538. Gruet's business contacts included André Philippe, a noted opponent of Calvin and the son of Jean Philippe, who had been executed in 1540. At the time of his death, Gruet lived in a large house at Place du Bourg-de-Four near Porte du Chastel and St. Pierre Cathedral. He may have served as a monk earlier in his life.
On June 27, 1547, a threatening note was found on St. Pierre Cathedral. Gruet's home was searched and papers were found which showed Gruet's opposition to the religious leaders of the town. On July 2, 1547, Calvin wrote a letter to his friend Pierre Viret in which Calvin stated that although many suspected Gruet of writing the note, the note was not in Gruet's hand. Calvin further stated that the search of Gruet's papers uncovered a number of documents which Calvin described as follows: "a humble petition which he had designed to present to the people in the Assemblies, in which he contended that no offence should be punished by the laws but what was injurious to the state; for that such was the practice of the Venetians, who were the highest authority in the matter of government; and that in truth there was danger with this city submitted to be ruled by the brain of one man of melancholy temperament, of a thousand citizens being destroyed in the event of any outbreak. Letters were also found, clearly written to Andre Philippe, and to others. In some he named me; at other times, he had enveloped me in figures of speech, so clumsily contrived, however, that one could lay his finger on what he meant to conceal. There were, besides, two pages in Latin, in which the whole of Scripture is laughed at, Christ aspersed, the immortality of the soul called a dream and a fable, and finally the whole of religion torn in pieces. I do not think he is the author of it; but as it is in his handwriting, he will be compelled to appear in his defence, although, it may be, that he has himself thrown into the form of a memorandum according to the turn of his own genius, what he heard from others;" Imprisoned for a month, he was tortured and confessed to libeling Calvin, but did not name any accomplices.
