The story
In Persia the vizier Haman cast lots (purim) to choose a day for destroying every Jew in the empire. Queen Esther, who had hidden that she was Jewish, was urged by her cousin Mordecai to go uninvited to King Ahasuerus, at the risk of her life, and reveal it. She did; Haman was hanged on the gallows he had built for Mordecai, and the day set for destruction became the day of deliverance. The Scroll of Esther, the Megillah, tells it and never mentions God by name.
It is the calendar's carnival: costumes, noise, drink and parody, and the one day on which the tradition tells its scholars to drink until they cannot tell Haman from Mordecai.
