Huginn and Muninn are depicted in either the classic smoothed-over style or spiral mixed pattern in stainless steel.
Munin and Hugin are brothers and the ravens of Odin. He sends them out into the Nine Realms each day to learn what was transpiring. They are the ones that tell Odin about the coming of Ragnarök. The connection between Odin and ravens is very old and very deep. Already in the sixth and seventh centuries AD – well before the beginning of the Viking Age in the late eighth century – visual depictions of Odin on helmets and jewelry frequently picture him accompanied by one or more ravens.
