For those of you getting into an argument about the historical mythology of Arthurian Legend . It is true for arguments sake that there are many Arthurian Legends. People wrote about him in the 1200's and Geoffrey wrote a version of the legend as well.
There is one and only one original compilation I have heard of called Le Morte De Arthur by Sir Thomas Mallory. He wrote this in the late 1400's (probably between the 1450's and when it was first published in 1485) and he put together the majority of historical stories and myths into one fairly succinct edition. This was to be the first in a series but I believe he only wrote the one book. Everything written about Arthurian Legend since is based pretty much on this text. So everything written since and all the references made to other writers and changes they have made are just that.
I think one of the charms of this series is that they have chosen to write their own version which you can choose to enjoy or not based on its historical accuracy. Remember it is a story like any other story and it is open to interpretation. One thing is for certain, they have changed the basics of the original tales but to me that makes it more interesting to watch.
I'm looking forward to the second season but I don't believe NBC will show it here as the ratings were awful so hopefully they'll release a DVD or we'll be able to see it on BBC America. Thanks for reading...
