Jacques Clement, a French regicide, born in Champagne about 1505, killed at St. Cloud, Aug. 1, 1589. He was a monk, and was selected at the suggestion of Bourgoing, prior of the convent of the Jacobines at Paris, as the instrument of the duke de Mayenne and the other leaders of the league for the assassination of Henry III. After having spent July 31, 1589, in fasting, and partaken of the eucharist, Clement went the next morning to St. Cloud, where, as the bearer of a letter from Achille de Harlay, he was admitted to the palace. While Henry III. was reading the letter Clement stabbed him. The king, throwing the knif'e which had inflicted a mortal wound into the murderer's face, exclaimed, "Oh, the wicked monk! he has killed me. Put him to death." The attendants killed him on the spot, and his remains were dragged in the mire, quartered, and burnt. The king died next morning, and Clement was proclaimed a martyr by Bourgoing, and by Peres Commelet, Guignard, and Mariana. The last named published De Rege et Regis Institutione (1599), in glorification of the regicide.
