Necklace Odin's Ravens.
Let’s begin with an explanation of what their names mean. Hugin (Old Norse Huginn) is translated as “thoughts,” while Munin (Old Norse Muninn) roughly translates as “memory” or “mind.” The ravens flew daily over Midgard (old Norse Miðgarðr), collecting crucial information and bringing it back to Odin.
It has been told that Odin was also called raven-God (old Norse Hrafnaguð), among many other names. Odin gave his ravens the ability to speak so they could provide him with the information he sought.
Each morning, Odin sends the ravens Hugin and Munin to race over the world of Midgard and report back what they have seen. The first to return wins Odin's favor. They looked and listened throughout the realm of men for the most exciting things to bring back to the All-Father.
The two ravens were often seen perching on Odin’s shoulders while they told him about the things they learned in Midgard.
