In Norse mythology, Hvergelmir (Old Norse "bubbling boiling spring") is a major spring. Hvergelmir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In the Poetic Edda, Hvergelmir is mentioned in a single stanza, which details that it is the location where liquid from the antlers of the stag Eikþyrnir flow, and that the spring, "whence all waters rise", is the source of numerous rivers. The Prose Edda repeats this information and adds that the spring is located in Niflheim, that it is one of the three major springs at the primary roots of the cosmic tree Yggdrasil (the other two are Urðarbrunnr and Mímisbrunnr), and that within the spring are a vast amount of snakes and the dragon Níðhöggr.
Hvergelmir is attested in the following works:
Hvergelmir receives a single mention in the Poetic Edda, found in the poem Grímnismál:
This stanza is followed three stanzas consisting mainly of the names of 42 rivers. Some of these rivers lead to the dwelling of the gods (such as Gömul and Geirvimul), while at least two (Gjöll and Leipt), reach to Hel.
vina, vegsvinn, thjodnuma
rivers born of hvergelmir
bjöll, strön, ylgr, leiptr
born of the great valhall
all of them flow
in the lands of midgardr
last they go deep
flow down into hel
under the left root of yggdrasil
lies the place for the old and the weak
when ragnarök comes swords will rise again
thousands of bodies arise
warriors march to the fiery pits of hel
the gates are wide open
fenris will break free, splitting the skies
surtr brings fire from the south
ruled by the daughter of loke
hel was her beautiful name
the rivers run blood of the weak
realm of ancient souls
nifelheim
the grave for the fools
odin's men didn't sleep there
below hel
a place for betrayers
the ultimate punishment
