Eventually I stumbled on Odin’s fylgja, the two ravens, Huginn and Muninn, thought and memory. He sends them every day across Midgard to bring him news of it. And each day he worries that they will not return.
I was amused. Today we know that crows/corvids are indeed quite clever and capable of both thought and memory. They have earned their legendary titles. They can do an awful lot of clever stuff. They can figure out how to complete a task using a series of tools in ways that require them to reason. They cache and store food away, and then recover it, They modify their caching behaviour depending on whether or not another crow watches them showing they can infer about the state of knowledge of another creature, something human children learn only after four years or so.
Huginn and Muninn, thought and memory, then became my next word beast project. The ravens are made from the science that investigates their cognitive abilities, their ability to think thoughts and make memories.
