Saint Genevieve
January 3
Saint Genevieve is invoked against fever. Born about the year 422 at Nanterre near Paris, she was consecrated to God as a young girl by Saint Germanus of Auxerre and gave herself to a life of prayer, fasting, and works of charity. When the armies of Attila the Hun advanced on Paris in 451, she urged the terrified citizens not to flee but to remain, fast, and pray, and the Huns turned aside from the city — an event for which she has ever since been honored as the patroness and protectress of Paris. She died about 512 at a great age. Her intercession was invoked in times of disaster, drought, and epidemic, and most famously during the outbreak of ergotism known as the mal des ardents (“burning fever”) in 1129, when the sick were said to be healed after her relics were carried in procession through the city; from this she became widely invoked against fever. Her feast is kept on January 3. Source: catholic.org.
