By 1504, Philibert died of pleurisy. Grief-stricken, Margaret threw herself out of a window, but was saved. After being persuaded to bury her husband, she had his heart embalmed so she could keep it with her forever. The Dowager Duchess cut off her long blonde hair and donned widow's clothing. She considered taking religious vows for a while, but instead endowed the construction of a monastery at Brou with an elaborate tomb for Philibert and herself with the words "FORTUNE. INFORTUNE. FORT. UNE" ("Fortune strongly persecutes a woman").
