 Here the earth is personified as the goddess Jörð, mother of Thor, enemy of the Jǫtnar or "giants".The practice of forming kennings has traditionally been seen as a common Germanic inheritance, but this has been disputed since, among the early Germanic languages, their use is largely restricted to Old Norse and Old English poetry.A possible early kenning for "gold" ("walha-kurna" "Roman/Gallic grain") is attested in the Proto-Norse runic inscription on the Tjurkö (I)-C bracteate.
