Numbers are significant in Norse mythology although not to the extent which they are in some traditions e.g. as in Jewish cabbalism.

Particularly significant numbers are three, eight and nine.

###
**Three**

The number three is both an invocatory and magic number:

- When Loki is bound with the entrails of his son, the entrails are wrapped thrice around the rock.
- The jaws of the wolf Fenrir are bound three times round to hold him by Tyr

The number three occurs with great frequency in grouping individuals and artefacts:

- There are three Norns.
- Yggdrasil has three roots, and three is the square root of the number of worlds on Yggdrasil, nine.

###
**Eight**

The number eight is highly potent and arguably the most magically potent of the numbers.

- Odin's steed, Sleipnir, has eight legs.
- Odin's ring Draupnir gives forth eight more similar rings every
*ninth* night.

###
**Nine**

The number nine is a magically significant number:

- When Odin sacrificed himself to himself, he hung upon the gallows for nine days and nine nights
- There are nine worlds on Yggdrasil;
