Odin's Staff and Aurvandil's Toe: The Wanderer
The brightest star in the constellation of Orion - his right "knee" or "foot", depending on how you see it - is classically named Rigel. The Old Norse people referred to it as Aurvandil's Toe. Aurvandil was a "star-hero" who often journeyed on adventures with Thor; on one of those adventures they crossed the freezing river Elivagar and one of Aurvandil's toes froze. Thor broke it off and threw it into the heavens, where it became this star.
As Aurvandil's Toe, the star brings riches and honors in return for diving into the unknown. As Odin's Staff, it is bound up with teaching and educating, and is often found strongly in the charts of famous teachers. This is Odin's wandering aspect, the Odin who goes in search of knowledge and wisdom, the Old Man with the wizard's staff seeking the hidden facts and bringing them back for everyone to see. It is a very different side of Odin than the warrior or the All-Father, but all these stars are His.
