In the Kalevala rune entitled "Haava" (The Wound, section 8),Väinämöinen attempts a heroic feat that results in a gushing wound, the blood from which covers the entire earth. This deluge is not emphasized in the Kalevala version redacted by Elias Lönnrot, but the global quality of the flood is evident in original variants of the rune. In one variant collected in Northern Ostrobothnia in 1803/04, the rune tells:
Matti Kuusi notes in his analysis that the rune's motifs of constructing a boat, a wound, and a flood have parallels with flood myths from around the world.
According to Anna-Leena Siikala, Väinämöinen's legs are of mythological and cosmogonic significance throughout Finnish mythology. For example, it is originally on Väinämöinen's knee that the primordial water-fowl first lays the world egg.
