Saint Romuald, whose aim was to restore the primitive rule to the Order of Saint Benedict, succeeded in founding some hundred monasteries in both Italy and France, and he filled the solitudes with hermitages. The principal monastery was that at Camaldoli, a wild, deserted region, where he built a church, surrounded by a number of separate cells for the solitaries who lived under his rule; his disciples were thus called Camaldolese. For five years the fervent founder was tormented by furious attacks by the demon. He repulsed him, saying, “O enemy! Driven out of heaven, you come to the desert? Depart, ugly serpent, already you have what is due you.” And the shamed adversary would leave him. Saint Romuald’s father, Sergius, was moved by the examples of his son, and entered religion near Ravenna; there he, too, was attacked by hell and thought of abandoning his design. Romuald went to visit him; he showed him the error of the devil’s ruses, and his father died in the monastery, in the odor of sanctity.
