Akton
Akton: A demon of disease that afflicts the ribs and lower back of mortals, tormenting them with aches and pains. He is one of thirty-six demons associated with the decans of the zodiac named in the pseudepigraphal Testament of Solomon. According to this text, Akton can be put to flight with the names Marmaraôth and Sabaôth. Although the origin and meaning of Marmaraôth is unclear, Sabaôth is one of the Hebrew names of God and means “Lord of Hosts.”
