Alath: A truly fearsome spirit whose name appears in the extra-biblical Testament of Solomon. Alath is a demon of illness said to attack children.
He steals their breath, causing asthma, coughs, and other labored breathing. He is the twenty-first demon of those associated with the thirty-six decans of the zodiac, and he is said to have the body of a man with the head of a beast. According to the Testament of Solomon, he can be driven off by invoking the name Rorêx.
