[4] Þjalfi ‘Þjálfi’: In a few myths (those about Þórr’s encounters with Hrungnir and Útgarðaloki), Þjálfi is the servant and companion of Þórr. In this particular version of the Geirrøðr myth, this is the first stanza to mention Þjálfi by name. See Introduction above for Þjálfi and his role in the myth about Geirrøðr. Despite much research (see ARG II, §428), this figure remains opaque, and none of the etymological speculations (most recently by Kiil 1956, 126-7) are convincing (for the homophone þjálfi ‘enclosure’, cf. Note to st. 18/4).
