Penelope
In Greek mythology, she was the wife of Odysseus, mother of Telemachus, and a model of fidelity. Pursued by suitors during Odysseus' absence at the Trojan War, she agreed to marry after she finished weaving her father-in-law's (Laertes) shroud, but she unraveled her work each night. Each night, for three years, she undid what she had woven during the day, but one of her maids discovered this secret and told the suitors. She finally promised to marry the man who could bend Odysseus' bow, but none could. Odysseus returned at this time disguised as a beggar, bent the bow, and slew the suitors.
