Frankly, I don't see this as a juvenile. It may be of interest to adults whose enthusiasm for folk material is on an intellectual and scientific basis, but not for youngsters, whose interest lies in the stories and the heroic stature of the exploits. Old Vainamoinen, the wizard singer, old Ilmarinen, the smith, are lascivious old men; Jankahainen, the young singer, is a braggart who can't bring it off. The morals and the ethics are contradictory. The stories are involved.
