In the myth of Utgard-Loki, Thor and friends visit the castle Utgard, where several beings have nearly identical names:
- Utgard-Loki, a giant and the ruler of Utgard
- Loki, an Aesir and the half-brother of Thor
- Logi, another guest, the personification of fire
Is there any deeper meaning to these similar names? Do the beings have a mythological or etymological connection? Is it simple wordplay, or coincidence? I know that Loki and Utgard-Loki are both associated with giants, and that Loki and Logi are both associated with fire. Is there more to it than that?
