[3] bergrisar ‘mountain giants’: Old Norse tradition differentiates between several types of giants (cf. Schulz 2004, 29-37). Jǫtunn, þurs and risi are old words and are attested in all Germanic languages. Trǫll is attested only in Scandinavian languages and with a younger dating. Apart from some giants who are connected to the gods in Old Norse mythology by marriage or blood, the giants are generally regarded as threatening. They are demonised as forces of chaos and embody the forces of nature. The group of the mountain giants is attested in the eddic poem Grott (st. 9), but is otherwise mentioned relatively seldom. The mountain giants were probably first established as a separate group by Snorri Sturluson in Gylf (Schulz 2004, 44-5).
