Most of the primary sources are actually quite boring, the way they werejux said:Finnish Kalevala and Estonian Kalev's son are the most ethnic legends of these nations, but they are not much of a page-turners.
compiled and written usually runs contrary to the expectations of today's
readers, which is why even very famous ones are only rarely bestsellers.
Germany's national epos is the Nibelungenlied, but the number of people
who did read its translation into modern German voluntarily is certainly
quite low, and I have little doubt that this is the same with other primary
sources - they only become popular once Hollywood & Co. have provided
a streamlined modernized (often mis-) interpretation of the original mate-
rial.
