In Norse mythology, Huginn (“thought”) Muninn (“memory”) are a pair of ravens that fly all over the world, Midgard, to bring information to the god Odin. In the Poetic Edda, a disguised Odin expresses that he fears that they may not return from their daily flights. The Prose Edda explains that Odin is referred to as “raven-god” due to his association with Huginn and Muninn, who are described as perching on his shoulders. Odin also gave the ravens the ability to speak.
Stolas is a Great Prince of Hell, commands twenty-six legions of demons (twenty-five according to other authors), and teaches astronomy and the knowledge of poisonous plants, herbs and precious stones. He is also known as Stolos and Solas. He is depicted as either being a crowned owl with long legs, a raven, or a man.
