Well MOCS you got me [thumping chest] right here, man. Malory Le Morte is pretty much my base for my comment. That plus Once & Future King, then Stewart and of course Tolkien. But yeah, Malory. A+, amigo.
Thanks SID. An A+ from you is legit as it get.
Regarding the other books you mention - exactly. Also, I considered citing Geoffrey of Monmouth's
Historia Regum Britanniaeas as my primary source, but I think his work is too narrow, even though it is older. Rather, I believe that GRMM was inspired mainly by Malory's work. I have some thoughts, but they are still raw.
1) GRRM has already said that
the Wars of the Roses inspired him in many ways.
2) Thomas Malory of Newbold Revel & the writing of
Le Morte d'Arthur were contemporaneous with the Wars of the Roses.
3)
Le Morte d'Arthur was first a curation from many existing sources (including Monmouth) and then retold in various stages of authenticity. Thus, it contains a greater number of seeds to choose from.
4) While many modern viewers and readers are shocked by the graphic nature of
ASOIAF (e.g. rape, incest, extreme violence, misogyny, age of protagonists/victims, etc.) this is all common place in
Le Morte d'Arthur.
5) Another element that distinguishes GRRM from many of his contemporaries, is his willingness to kill off major characters. Again, this is quite common in Malory. In fact, in
Le Morte characters may die in early tales and then reappear quite healthy in later scenes - with no explanation given. Of course, this is primarily related to the curated-from-many-sources element of
Le Mort, but it sets a tone that GRRM picks up on - imo.
Now, how does this relate to the TV series? Well,
Le Mort is kind of a compilation of many older tales that served a similar role to comic books. They were common characters used as archetypes of a sort, that were then written/spoken about by the many story tellers of the time. Often, these stories conflicted or did not follow a linear timeline or even reality-line. It had a multiverse aspect to it.
In the TV show, many of the eccentric and or even stupid things that characters may do, I explain away as part of the comic book element. It may be shallow in one area, but deep in another. Sometimes, in order to be deep on one aspect, I think the other needs to be shallow.
I dunno - as usual. But, using this outlook, I absolutely love the TV series.
