Midgard

The runes a:miþkarþi, Old Norse á Miðgarði, meaning "in Midgard" – "in Middle Earth", on the Fyrby Runestone (Sö 56) in Södermanland, Sweden.

In Germanic cosmology, Midgard (an anglicised form of Old Norse Miðgarðr; Old English Middangeard, Old Saxon Middilgard, Old High German Mittilagart, and Gothic Midjun-gards; "middle yard", "middle enclosure") is the name for Earth (equivalent in meaning to the Greek term οἰκουμένη : oikouménē, "inhabited") inhabited by and known to humans in early Germanic cosmology. The Old Norse form plays a notable role in Norse cosmology.
