Some researchers have presented theories about stev "relating to language and poetry rather than to slowed-down dance": Ivar Mortensson-Egnund (in 1914), Idar Handagard (in 1942), O.M. Sandvik, Eivind Groven (1971), Jon Storm-Mathisen (2002 and 2007) and Jacqueline Pattison Ekgren (1975 and 2007) [REF].
