Gangleri (ON, ‘the one tired from walking’?). A name for Odin in the GrÍmnismál 46 and in the Ížulur. Snorri also says that Gylfi who comes to the Gods (Gylfaginning 2) is called Gangleri, but he is definately not identical with Odin. The name Gangleri is clearly connected with Odin’s frequent role as a wanderer.
