Which historical figure do you think Turin embodies? I personally see a connection with Sigurd and the Volsung lineage, I have some notes on my reasoning sitting in my study area, I'll make a follow up in this thread and in the one on Aragorn when I get home to access my notes and texts.

If I remember the story correctly, I would say Kullervo from the Kalevala.
