Antero Vipunen is a giant who appears in Finnish mythology and Kalevala folk poetry.
In order to obtain them, he goes to wake up the sleeping Vipunen by pushing sharp stakes into his grave and through his mouth and stomach.
In 1938, the Finnish composer Uuno Klami wrote the symphonic poem Vipusessa käynti (In the Belly of Vipunen), for baritone, men's chorus, and orchestra.
This piece, which musically depicts the Väinämöinen-Vipunen story described above, received its world premiere recording by the Finnish conductor Sakari Oramo and the Finnish Radio Symphony Orchestra on the Ondine label (ODE859-2, 1995); the vocalists are Petri Lindroos and the Polytech Choir.
[1] Antero Vipunen also gave his name to a book edited by Yrjö Karilas, which contains various plays and games, and contains both general and specialised knowledge.
