In Swedish folklore Nature was animated by spirits.
They were not hostile, but could be tricky and
dangerous… You needed to be cautious and respectful
and not allow yourself to be allured…into their world…
“Näcken” was a water spirit who lived in running waters.
Folk musicians were thought of as his apprentices,
and violinists especially were considered the instruments
of the Devil in Christian times…they inspired dancing
and sex between men and women not married…
Children and women were warned not to get too
close to these waters or he might enchant them and
pull them down to his realm…
