Born in Africa, Zeno was a bishop of Verona who loved to fish in the Adige river. He was a notable preacher and wrote much about baptism. When he was born, a demon took his place in his crib, and though he was suckled for eighteen years, he never grew. In the meantime, Zeno was raised by monks. When he was coincidentally sent by them to investigate this phenomenon, he forced the demon to spit up all the milk he had consumed into a great vat.
