þríhyra

Þríhyra is an Icelandic word that literally translates to "three-headed." It is most commonly used to refer to a creature or entity possessing three distinct heads. While not a universally recognized mythological figure, the concept of a three-headed being appears in various mythologies and folklore across different cultures, often symbolizing immense power, divine authority, or a formidable adversary.

In Icelandic folklore specifically, þríhyra might appear in tales of trolls, giants, or other supernatural beings. The presence of multiple heads can signify enhanced senses, a greater capacity for thought or speech, or a more terrifying appearance. The specific context in which a þríhyra is described would determine its exact nature and role within a narrative. It is not a singular, established character but rather a descriptive term for a type of multi-headed creature.
