Genevieve

Born around 419 near Paris, Genevieve met two traveling bishops as a child and vowed herself to lifelong virginity. Miracles and healings clustered around her early; locals said she could change the weather. After her parents died she moved to Paris, where her piety drew both devotion and hatred - the city nearly killed her before one of those same bishops intervened. In 451 her prayers supposedly spared Paris from Attila's army, a "prayer marathon" that became her signature act. She spent her later years building: a basilica for Saint Denis in 475, another for Peter and Paul around 500. She died sometime after 502. Centuries later Paris made her official patron, and for nine hundred years the city hauled out her reliquary whenever catastrophe loomed - 153 public invocations between 885 and 1791, each shaped by the crisis of the moment. The Revolution ended the tradition, and it never quite came back.
