Born to Francesco I de' Medici, Marie married Henry in 1600, and was crowned Queen of France ten years later with the Rose Scepter, which disappeared afterwards. Some say that she wanted to be the last queen to hold it and had made it disappear. The day after her coronation, Henry was assassinated by François Ravaillac, leaving the queen a widow.
In 1612, she purchased houses from the Duke of Piney-Luxembourg to build a lavish palace designed by Salomon de Brosse, intending to call it the Medici Palace. The Parisians hated Marie however, and insisted on calling it the Luxembourg Palace. The rumors about the Rose Scepter proved true, as Marie was buried with it in Saint-Denis. During the French Revolution, as raiders looted the royal tombs of Saint-Denis, the Assassin Arno Dorian recovered the scepter to keep it from falling into the hands of the raiders, and kept it as a weapon.
