Hillervo and
Juoletar are a pair of water related
haltijas known from one runic song collected by Christfried Ganander. He identified Hillervo as the Mother of Otters and Juoletar as her husband, a beautiful man and Finnish
Neptune. This has awoken a lot of questions among researchers, as they don't appear in other runic songs, and Juoletar is an explicitly feminine name with the final suffix
-tar. According to
Martti Haavio's theory, Hillervo was originally the Mother of Polecats, but as polecats only lived in Finland between the 13th and 17th centuries (before returning in the 20th century), Hillervo of polecat hunting spells was reutilized in otter hunting spells. Haavio connected the name Juoletar to the name
Kuolari mentioned in a
Ladoga Karelian,
Karelian language otter-hunting song, believing it to have originally been *
Juolari. Therefore, Juoletar would be the original Mother of Otters, or the Elder of Otters (whether the rune singer referred to Juoletar as a mistress or a king). Some researchers, such as Haavio and
Matthias Castrén, have supported the theory that Hillervo would be the same goddess as
Tellervo. Haavio suggested her name could come from either the word 'trap' or 'polecat', finding the latter theory more likely.
Kaarle Krohn suggested origins in '
cloudberry' and as well. Krohn also suggested a connection to Hilasatar, maiden of
Hiisi, mentioned in a
Kainuu runic song describing the origin of copper (sharing similarities with the runic songs describing the origin of the
common lizard). In Krohn's opinion, these names could be connected to
Saint Hilarius. The name Juoletar has been theorized to come from either '
bog bilberry', known in
Swedish as 'otter berry', or the word '
oxbow lake'. Haavio thought these two words could be connected to each other, further connecting to an older name of the otter or a description of an otter's place of living (calling 'river fork which periodically dries up').
