Mortal Karelian-tribal chief, brother of Kalervo and the prime antagonist of the Kullervo-cycle. Driven by a fratricidal feud, he raised a war-band and slaughtered the whole Kalervo kindred save one pregnant captive, who bore Kullervo in slavery; he tried repeatedly to kill the preternaturally strong infant (drowning, burning, hanging) and, failing, sold the boy to the smith Ilmarinen. The wrong he began is the wrong the cycle avenges: Kullervo at last marches on Untamola, kills Untamo and burns his settlement (Runo 36). Wired as sibling of finnish_kalervo and enemy of finnish_kullervo, who slays him.
