A nasty demon who shows up in an Apocryphal book from the Old Testament called the The Book of Tobit, and is referred to in the Talmud as the King of Devils. In the The Book of Tobit, Asmodeus falls in love with a woman named Sara, and he kills her husband every time she marries on their honeymoon. This happens seven times. On the eighth time, she marries Tobias, who was warned of Asmodeus by the angel Raphael. Tobias, with the aid of Raphael, creates a charm from the heart and liver of a fish that was burned on ashes, and this charm causes Asmodeus to be banished away to Egypt (which was, at the time, the most horrible and distant land the Israelites could think of). In Paradise Lost, he was described as smelling and looking like a fish.
