[9][8] A poem, by 11th-century Icelandic skáld Þjóðólfr Arnórsson, manages to use all four above mentioned terms in a single poem about Sigurd the dragon slayer, based on a fight between a blacksmith and a leather worker, which Arnórsson supposedly composed spontaneously upon request:[10] Sigurðr eggjaði sleggju / snák váligrar brákar, / en skafdreki skinna / skreið of leista heiði.
/ Menn sôusk orm, áðr ynni, / ilvegs búinn kilju, / nautaleðrs á naðri / neflangr konungr tangar.
[16] The Old Norse Eddic poem Fáfnismál, written around 1270, tells an alternate version of the same root story as Nibelungenlied, were the dragon, Fáfnir, is described as flightless and snake-like, and is referred to as an ormr.
[19] Both of these descriptions are consistent with 11th century depictions of Fáfnir as a runic animal on various picture stones, sometimes being limbless and other times featuring various forms of limbs.
[20] The evolution of wingless and legless worms and lindworms to flying, four-legged romanesque dragons in Germanic folklore and literature is most likely due to influence from continental Europe that was facilitated by Christianisation and the increased availability of translated romances.
It has thus been proposed that the description in Völuspá of Níðhöggr with feathers and flying after Ragnarök is a late addition and potentially a result of the integration of pagan and Christian imagery.
[33] Among local legends and tales: The association between dragons and hoards of treasure is widespread in Germanic literature, however the motifs surrounding gold are absent from many accounts, including the Sigurd story in Þiðreks saga af Bern.
[34] A motif could potentially be an old myth in Germanic folklore, were it is said that which lies under a lindworm will grow at the rate of the snake, thus they brood over treasure to get richer.
A quote from Fru Marie Grubbe by Danish author Jens Peter Jacobsen (1876), here given in its Swedish (1888), and English (1917), translation, due to availability.
Men det skedde icke, och han kunde icke låta bli att tänka sig, att dessa outtalade förebråelser nu lågo som lindormar ligga i sina mörka hålor, rufvande öfver dystra skatter, som växte allt efter som ormarna växte, blodröd karbunkel, lyftande sig fram på guldröd stjelk, och blek opal, långsamt utvidgande sig i knöl på knöl, svällande och ynglande, under det ormarnas kroppar, stilla, men ohejdadt växande, gledo ut i bugt på bugt, lyftande sig i ring på ring öfver skattens frodiga hvimmel.
[36] In the Völsung Cycle, Fáfnir was a dwarf, who, upon claiming a hoard of treasure, including the ring Andvaranaut, transforms into a dragon to protect and brood over it.
Fáfnir's brother, Regin reforges the sword Gram from broken shards and gives it to the hero Sigurd who uses it to kill the dragon by waiting in a hole until the worm slithers over and exposes his underbelly.
Sigurd then cooks and tastes the dragon's heart, allowing the hero to understand the speech of birds who tell him to kill Regin, which he does and then takes the hoard for himself.
[13] In Beowulf, the dragon that the poem's eponymous hero is awoken from the burial mound in which it dwells when a cup from its hoard is stolen, leading it to seek vengeance from the Geats.
[39] The motif of gold causing a snake-like creature to grow into a dragon is seen in the Icelandic tale of the Lagarfljót Worm recorded in the 19th century.
[30] A similar creature from later Orcadian folklore is the attery stoor worm which was killed by the hero Assipattle, falling into the sea and forming Iceland, Orkney, Shetland and the Faroe Islands.
[51] The killing of Fáfnir is also potentially pictured on four crosses from the Isle of Man and a now lost fragment, with a similar artistic style, from the church at Kirby Hill in England.
[59] Wooden carvings from the Hylestad Stave Church of scenes from the Völsunga saga include Sigurd killing Fáfnir, who is notably shown with two legs and two wings.
