What do you think of a fight depicted one way in primary sources and other supplementary sources about ten years ago, but in recent years, a lot of supplementary sources have stated something else about the fight, meaning that there's a noticeable shift in the opinion of the tertiary writers? What takes precedence then? Is the other simply dismissed without merit?
Ah, so you're one of those who thinks that even 10-1, supplementary material can't override the main source.
Do you think it's acceptable to argue in certain cases that we should take the tertiary sources, since it's our interpretation of the primary source that appears to conflict, and that this may not have been the author's intent? Of course, this only applies to things that aren't set in stone.
