How many ravens does Odin have?

The story behind the answer

Two: Odin’s ravens are Huginn (“Thought”) and Muninn (“Memory”). Each day they fly over the worlds to gather news and return to perch on Odin’s shoulders, whispering what they’ve seen. This makes Odin the all-knowing Allfather not by magic alone, but by intelligence-gathering.

The Poetic Edda’s Grímnismál says Odin fears Muninn may not come back—showing how precious memory is. Remember it as two sides of the mind: Thought + Memory = 2 ravens. Bonus link: Odin also keeps two wolves, Geri and Freki—another pair.
