St. Foy is the saint whose intercession Gerbert attributed his healing to.

• A. St. Michael
• B. St. Foy
• C. St. Peter
• D. St. Augustine

Answer: (B)

Healing in medieval belief often depended on a saint’s intercession, a bridge between the petitioner and the divine. Saint Faith, known as St. Foy, had a famous reputation for healing miracles at Conques, where many pilgrims sought her intercession and reported cures. The tale that Gerbert’s recovery came through St. Foy’s intercession fits this pattern, making her the best match for the story. The other figures—St. Michael the archangel, St. Peter, and St. Augustine—are important in their own right, but they’re not the saint most closely linked to this particular healing narrative in Gerbert’s tradition.
