**Stanza 39:** Thor says that some women that he killed were she-wolves and taht they chased Þjálfi.
Þórr said:
39. ‘They were she-wolves, and scarcely women;
they smashed my ship, which I’d shored up,
threatened me with iron clubs, and chased Þjálfi!
What were you doing meanwhile, Hárbarðr?’
Chapter 44-45(p.38): Thialfi is introduced as a peasant's son. He breaks one of Thor's goat's leg bones to get at the marrow. As atonement, he and his sister Röskva become Thor's servants.
The farmer’s son was called Thialfi, his daughter Roskva. Then Thor placed the goatskins on the other side of the fire and instructed the peasant and his household to throw the bones on to the goatskins. Thialfi, the peasant’s son, took hold of the goat’s ham-bone and split it open with his knife and broke it to get at the marrow. [...] And when he saw their terror then his wrath left him and he calmed down and accepted from them in settlement their children Thialfi and Roskva, and they then became Thor’s bondservants and they have attended him ever since.
Chapter 46(p.41-42): At the court of Útgarða-Loki, Thialfi competes in a running race against a figure named Hugi. He loses three times.
‘Then Utgarda-Loki asked what that young man there could perform, and Thialfi said that he would attempt to run a race of some kind with anyone Utgarda-Loki put forward. He said, Utgarda-Loki, that this was a good feat [...] Then they began the first race, and Hugi was so far ahead that he turned back to meet him at the end of the race.
Chapter 47(p.45): Útgarða-Loki reveals that Thialfi's opponent, Hugi, was the personification of Thought, which is why he was impossible to beat.
‘And when Thialfi competed at running with the one called Hugi [thought], that was my thought, and Thialfi was not likely to be able to compete with its speed.
Chapter 3-4(p.72): A kenning for Thor is "lord of Thialfi and Roskva." A verse by Eilif is quoted where Thialfi is called "Roskva's brother."
How shall Thor be referred to? By calling him [...] lord of Thialfi and Roskva...
Eilif said this:
Roskva’s brother [Thialfi] stood enraged, Magni’s father struck a victorious blow. Neither Thor nor Thialfi’s power-stone [heart] shakes with terror.
Chapter 17(p.78-79): Thialfi accompanies Thor to his duel with the giant Hrungnir. He acts as Thor's second, tricking the giant into lowering his shield by giving him false information about Thor's attack.
Thor went to keep his appointment for the duel, and with him Thialfi. Then Thialfi ran on ahead to where Hrungnir was standing and said to him:
‘You are standing unguardedly, giant, you’ve got your shield in front of you, but Thor has seen you and he is travelling by the lower route underground, and he is going to come at you from below.’
Chapter 18(p.83): In a verse from Þórsdrápa, Thialfi is referred to by the kenning "battle-Rognir".
Full of perjury, the cargo [Loki] of incantation-fetter’s [Sigyn’s] arms was on his way sooner with the company’s leader than the battle-Rognir [Thialfi].
Chapter 18(p.84): Another verse from Þórsdrápa mentions Thialfi accompanying Thor as one of the "pool-riders" [river-crossers].
And then the allied sword’s help haters waged shield’s hard-fetter-[strap-]board’s [shield’s] din [battle] against slope-Hords [giants], before the pool-riders [river-crossers, Thor and Thialfi]...
