In the sagas, Einarr is attributed several characteristics that are associated with Odin. These include:
One Eye: Both Einarr and Odin are described as having but one eye. This is a notable physical characteristic that links them, as seen in sources like Wikipedia's articles on Torf-Einarr and Orkneyinga saga.
Relentless Seeker of Wisdom: Odin is known for his insatiable thirst for wisdom, which is reflected in Einarr's actions and demeanor. This is highlighted in an article from Einarr's Journey, which discusses Odin's pursuit of knowledge.
Warrior Attributes: Einarr, like Odin, is portrayed as a formidable warrior. The death of an opponent at Einarr's hands is offered to Odin, indicating a connection between their martial prowess and the god of war and death. This is mentioned in the Orkneyinga saga on Wikipedia.
Magic and Poetry: Odin is revered as a god of magic, poetry, prophecy, and the hunt. While specific textual evidence linking these attributes directly to Einarr in the sagas is not provided in the search results, it is reasonable to infer that a character associated with Odin might share or reflect some of these qualities, given the cultural context.
These characteristics show that Einarr, in the sagas, is deeply connected to the attributes of Odin, reflecting the god's influence in Norse mythology and literature.
