Justin, yes it's the same theme, because I don't think that those profiles are written in stone, they can always be change depending on new findings, but until that appear, they due as a temporary solution. Plausible profiles are not any roadblocks, people will not stop discovering new pieces that will preserve or change the way it is laid out, but until something new arrives or a better solution evolves, we should use what we have, and see it just as a work in progress.
I think you're too much stuck with your head in the idea that contemporary sources are all that counts and nothing else is as valid, thus misses out that even a rewritten source, actually in most cases are a replacement of a contemporary source that has been damaged due to the ravages of time and needed to be rewritten in order to preserve it, and that oral tradition also at one point have been written down, which also not means that it has not any trace of value t all left, but at the contrary contains the value in not being written history.
In Scandinavia we had a tradition of skalds, most king had one and as they replaced each-other continuously so did the skalds, so we have had skalds covering the kings between the years 900-1250, and surely, before that as well as after that, but they finally got replaced at the same time people started to write down everything that they thought was important by themselves in form of their own selected historians, and if anyone writes down his own history or pay someone to do it, it will certainly be even more biased and contain more faults than if someone who already got paid and have finished his work just tell someone else what he actually have witnessed.
The operational center for this was Island, the Icelandic skalds had the training and skills and was highly appreciated in the courts all over Scandinavia, and when they went back they exchange their information with each other until it was written down, those list of kings are in fact just as good as any contemporary source, and in many cases, king named have been confirmed to have existed by other contemporary sources in other countries, it like, we have: A, B, C, where C is mentioned in a contemporary latin text found in another land, than we have D, E, where E is also named just in a way as C, then we have, F, and G, and everyone knows that G was real, in my mind, they are all real, proven by C, E and G, not fantasy, or mythological kings.
Nothing says that it was created as a fabrication when walking in real life beside all of those capital letters, there has been a skald documenting, who has served, got paid and finally brought his information back to Iceland, for generations transmitting and preserved their knowledge, so I find it tragic that some of the curators here, can't grasp this at all, dismissing it as more or less worthless, which at the same time just proves a headless lack of insight summoned up in; - I don't know anything, I can't validate it, I just cut the shit off, end of discussions!
