Among the Aesir gods in Norse mythology, the supreme god Odin, is frequently depicted sitting on his high seat, Hlidskjalf, in Asgard, the home of the gods.
Hugin is believed to represent ‘memory’, while Munin personifies ‘thought’. Every day, Odin sends them out and they fly across the worlds to seek for important news and events. Odin surveys the worlds from Hlidskjalf and must know reports of what is going on in all Nine Worlds. In the evening, Hugin and Munin return to Odin’s shoulders and during dinner in Valhalla, they whisper all they have heard in his ears.
