Thjazi (Thiassi, Tjazi, Thaffi) is one of the Norse Frostjötnar (frost-giants). His father is Alvaldi (“almighty”), his brothers Idhi (“the hard-working one”) and Gangr (“gait”), his mother is unknown. When Alvaldi died he left all his gold to his three sons. They divided it by each taking a mouthful so as to divide it equally. This is why the Eddic description “the speech of Thjazi, Idhi and Gangr” is a metaphor for gold itself.
Like most Jötnar Thjazi, who resides in Thrymheim, was a shape-shifter, and it was in the shape of a giant eagle that he made his first appearace in the Eddas. When Loki, Hönir and Wotan were traveling they got hungry and decided to cook one of the oxen they saw grazing on a meadow. As they began wondering why the oven did not warm they heard a voice from one of the trees above. It was Thjazi, who admitted he was prohibiting the oven from warming, but if they would share the oxen’s meat with them, he would gladly heat it up for them. They agreed. Yet when Thjazi went for the best and thickest shares of the meat Loki struck him with this staff so hard it clung to his side. Thjazi escaped high into the air, dragging both staff and Loki with him. Loki begged for mercy and Thjazi made him a peace offering. If he would bring him Iduna and her apples, he would spare Loki’s life.
Honoring his promise Loki lured Iduna out of Asgard, alleging that he had found even more miraculous and juicier apples than the ones she had. She should bring hers to compare them.
When eagle-shaped Thjazi kidnapped Iduna, the Gods began withering, growing old without Iduna’s magical apples of youth and strength.
When Loki was found out he borrowed Freyja’s falcon cloak and flew into Thrymheim and rescued Iduna. Thjazi, outraged, flew after him, but the Gods were already awaiting the Jotun.
They lit the walls and towers of Asgard on fire, burning Thjazi’s wings and killing him.
His daughter Skadi swore revenge and made her way to Asgard. Instead of avenging the murder of her father she settled with an Aesir husband (Njörd) and a “bag full of laughter” (which Loki provided). On top of that Wotan cast Thjazi’s eyes into the sky where they became stars, forever watching over the nine worlds. The formation Auguthjaza is the only Nordic star constellation ever mentioned in the Eddas, yet which constellation in the sky is referred to remains unknown.
On a side-note, in the Ring of the Nibelungs it is not Thjazi but Fafir and Fasolt who kidnap Iduna with a completely different background story as well. This as a small reminder that different Germanic countries have different mythologies, folk tales and lore which are all equally important and “true”.
Etymologically Thjazi might derive from Sanskrit Twast(i)r, one of the chief Gods in Hinduism. In one of the early myths Twastr steals the “divine drink” of the Gods. Later on in the Vedanta and other texts there was no mention of him in bird-form anymore though, yet he was often accompanied with the giant bird Garruda or the God Indra in bird-form.
