Haustlöng  Haustlǫng (Old Norse: 'Autumn-long'; anglicized as Haustlöng) is a skaldic poem composed around the beginning of the 10th century by the Norwegian skald Þjóðólfr of Hvinir. The poem has been preserved in the 13th-century "Prose Edda" by Snorri Sturluson, who quotes two groups of stanzas from it and some verses to illustrate technical features of skaldic diction. Snorri also who drew inspiration from Þjóðólfr to redact his own version of the myths told in "Haustlöng". The poem describes mythological scenes said by the skald to have been painted on a shield: Loki's betraying of Iðunn, the Æsir's "old-age cure", who was snatched from them by the eagle-shaped jötunn Þjazi; and Thor's victorious combat against the strongest of the jötnar, Hrungnir. The title of the poem, "Haustlǫng", translated as 'Autumn-long', may refer to its period of composition or gestation by the skald, identified from a relatively early period with Þjóðólfr of Hvinir. The stanzas 1–13 of the poem depicts the encounter of the Æsir (gods) Odin, Loki and Hœnir with the jötunn Þjazi in the form of an eagle. As the three gods Odin, Loki and Hœnir are trying to cook an ox, the eagle-shaped Þjazi asks for some. Loki strikes at him with a staff, but the latter sticks to the eagle and to Loki's hand as the bird flies out. The eagle then asks Loki to bring him the gods' "old-age cure", Iðunn. Without Iðunn, tells the poet, "all Ingi-Freyr’s kin [the Æsir] became old and grey in their assembly; the powers were rather ugly in form". Then the gods catch Loki and force him to get Iðunn back: "‘You shall be trapped, Loki,’ the angry one spoke thus, ‘unless by some scheme you bring back the renowned maid, enlarger of the fetters' [gods'] joy."
