In demonology Andromalius is a mighty Great Earl of Hell, having thirty-six legions of demons at his service. He can bring back both a thief and the stolen goods, punishes all thieves and other wicked people, and discovers hidden treasures, all evilness, and all dishonest dealing.

Andromalius is depicted as a man holding a big serpent in his hand.
