Henry II of France and Diana of Poitiers witnessing the execution of a Protestant
Henry II, though not of a cruel disposition, was induced by anger and wounded pride to join in the persecution of the Protestants through being brought in contact with one of his own domestics, whose resistance provoked his hatred to Protestantism.
The man chosen for this experiment by Diana of Poitiers and the Cardinal of Lorraine was a workman employed by the king’s tailor. This unfortunate man being brought into the King’s presence, defended his religious principles with great firmness and dignity, and interrupting Diana as she advanced to make a remark, he exclaimed, “Madam, rest satisfied with having infected France with your infamy, but touch not those things which appertain to God.” The King at these words, furious beyond control, swore he would see him burnt alive.
Henry was present at the execution, but was so overcome that he was obliged to leave the window. The martyr, enduring the horrible suffering with the greatest courage and firmness, kept his eyes fixed upon the King, who, horror-stricken and terrified, fied[sic], saying that never again would he witness so horrible a sight.” — Michelet,
