Ratatoskr, in Norse mythology, is a squirrel that runs up and down the world tree Yggdrasil, carrying messages between the eagle perched atop the tree and the serpent Níðhöggr, who dwells beneath one of the three roots of the tree. This cosmic squirrel is mentioned in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and in the Prose Edda, written in the 13th century by Snorri Sturluson.
The name Ratatoskr is commonly interpreted to mean "drill-tooth" or "bore-tooth", which may refer to the squirrel's habit of gnawing on the branches of Yggdrasil. Some scholars suggest that Ratatoskr's role in carrying messages between the eagle and the serpent represents the spread of gossip or malicious words, as the two creatures are often depicted as being in constant conflict. This interpretation paints Ratatoskr as a mischievous character who may enjoy stirring up trouble between the different realms connected by Yggdrasil.
While Ratatoskr plays a relatively minor role in the surviving Norse myths, his presence highlights the interconnectedness of the Norse cosmos and the constant communication between different realms and beings. The image of a squirrel racing up and down the world tree also serves as a vivid representation of the dynamic and ever-changing nature of the Norse mythological universe, where even seemingly insignificant creatures can play important roles in maintaining the cosmic balance.
The name Ratatoskr is commonly interpreted as "drill-tooth" or "bore-tooth" in Old Norse, likely referring to the squirrel's habit of gnawing on Yggdrasil's branches.
The exact origins of Ratatoskr are not specified in the surviving Norse myths. As a creature inhabiting Yggdrasil, it's possible that Ratatoskr came into being with the creation of the world tree itself, but this is not explicitly stated in the sources.
There is no information in Norse mythology about Ratatoskr's parents or any offspring. As a mythical creature, its familial relationships are not detailed in the surviving texts.
Norse myths do not mention any partners or lovers for Ratatoskr. Its role seems to be solely focused on its function as a messenger on Yggdrasil.
Ratatoskr is not associated with any specific items or weapons. Its primary tool is its ability to quickly traverse Yggdrasil and relay messages.
Ratatoskr is not known to have any mascots or companions. It operates independently in its role on the world tree.
While not possessing direct power, Ratatoskr's influence lies in its ability to spread information (or misinformation) between different realms of the Norse cosmos. Some interpretations suggest that Ratatoskr may enjoy stirring up conflict through the messages it carries.
Ratatoskr does not feature prominently in any specific Norse stories or sagas. Its presence is mainly noted as part of the description of Yggdrasil and the creatures that inhabit it.
