St. Marcel of Paris Invoked against vampires
Educated and ordained in Paris Marcel showed a flair for the dramatics, even in his youth, holding iron bars in his hands and turning water into wine. He was a welcome relief as bishop of Paris after his strict predecessor, Pudentius, and the city loved him. When a rich and dissolute woman was buried in a cemetery, a black serpent wormed his way out of her grave, exposing the corpse and nibbling on its grisly remains, which cause quite a scandal. Marcel, in full bishop regalia, with le tout Paris following him, confronted the ghoulish serpent. Ignoring its threatening hisses, the Saint clobbered the fiend with his staff, wrapped it in his robe and dragged it out of the cemetery.
