In Norse mythology, Hugin and Munin are Odin’s two ravens, symbolizing "thought" and "memory." Each day, they fly across the realms to gather knowledge and observe events, returning to Odin to share what they’ve seen and heard. Their constant surveillance of the world highlights Odin's pursuit of wisdom and his deep connection to both mental reflection and memory, making the ravens powerful symbols of his all-seeing and all-knowing nature.
