Helge! You wrote "At least the whole subject seems deeply shrouded in a cloud of confusion."
I would further complete your sentence by saying that history is/was deliberately shrouded in a cloud of confusion! Various "experts", each with his/her own agenda and opinions! Countless translations, mistake prone copies, deliberate obfuscation, etc.
Can we really give good countanance to these stories that have,over the centuries, become nothing more than fiction?
