When Attila was reported to be marching on Paris, the inhabitants of the city prepared to evacuate, but Ste. Geneviève persuaded them to avert the scourge by fasting and prayer, assuring them of the protection of Heaven. The event verified the prediction, for the barbarian suddenly changed the course of his march.
The life of Ste. Geneviève was one of great austerity, constant prayer, and works of charity. She died in the year 512. Her feast day is January 3rd.
One of the symbols of this Ste. Geneviève is a loaf of bread because she was so generous to those in need.
