This devil is strong in wile and might, as witches are in their craft; he makes men hunger and thirst and have sinful desires; he entices men to him with his breath; whoever follows him finds shame. It is the ones of little faith whom he deceives, not those who are strong and steadfast in flesh and spirit, holding to the true faith. He who listens to the devil's teachings will at last repent it sorely; he who fastens his hope on him will follow him to dim hell.
THE SIREN
Nature
In the sea are many wonders. The mermaid is like a maiden to the waist, but otherwise she is exactly like a fish with fins. This marvel dwells in dangerous places where the water is shallow, and she sinks ships and works harm thus. Merrily this maid sings, and she has many voices,—many and shrill,—but they are all evil, for sailors forget their steering because of her singing, and they slumber and sleep and wake too late; and the ships sink with the confusion, and come up nevermore. Wise men and wary know how to flee, and often escape with uncorrupted heart. By this maiden of whom you have heard, this monster half human and half fish, something is betokened.
Signification
Many men illustrate the meaning of this example: without, they wear the skin of sheep; within, they are wolves wholly; they speak piously, but wicked are their deeds; their deeds are all unlike what their mouths speak. Twofold they are in spirit,—they swear by the cross, by the sun, and by the moon, and they lie both in their speech and in their singing. They deceive thee then; they destroy thy goods with treachery and thy soul with lying.
