Arthurian Legend

I've done a rewatch of Merlin season one to write down all the importan
stuff that is treated strangely and with some mistakes in the future
seasons. I'll also rewatch the future season to see how the writers
treated what they had with the first season.

If you are interested:
Important
things about characters, their pasts, their relationships, food,
glasses, reactions and other in the first season of Merlin BBC.
( episode 1x01 )
( episode 1x02 )
( episode 1x03 )
( episode 1x05 )
( episode 1x06 )
( episode 1x07 )
( episode 1x08 )
( episode: 1x09 )
( episode: 1x10 )
( episode: 1x11 )
( episode: 1x12 )
( episode: 1x13 )

Conclusions:
The characters and The end of the season
Arthurian references (I was too good!)

Also: Season 1, season 2 and season 3: How many evil women are there in Merlin BBC?

Some random picspams (I was bored) about some actresses and actors who had arthurian roles in the past. I tried to use pics that were not arthurian related (I used arthurian related pics when I couldn't find any other ones).
(the names are from left to right, from up to down)

Arthurian actors: PICSPAM 1 (Guinevere, Morgan and Mordred)

Arthurian actors: PICSPAM 2 (Lancelot, Arthur and Kay)

Arthurian actors: PICSPAM 3 (Lady of the lake, Gawain, Galahad)

Arthurian actors: PICSPAM 4 (Igraine, Uther and Morgause)

Arthurian actors: PICSPAM 5 (Lot, Perceval, Merlin)

Rewriting this post because I've read more books!

Who is Mordred's mother? This is a list of ancient books I read and the parentage of Mordred.

HISTORIA BRITONUM: No Mordred.
ANNALE CAMBRIAE: There is Mordred/Medraut but there is nothing about his parents.
HISTORIA REGUM BRITANNIAE: Mordred is the son of Anna and Lot. Anna is Arthur's sister.
CHRETIEN DE TROYES: No Mordred. But we have a Morgana and no telling about her children.
CULHWICH AND OLWEN: Nothing of Mordred, Morgause or Morgana.
LANCELOT-GRAIL: I've read a modernization and Morgause was Mordred's mother.
ALLITERATIVE MORTE ARTHURE: Reading it : D I'll let you know.
MORTE d'ARTHUR: Mordred is the son of Morgause and Arthur

And now the modern books. In this color  the books with Morgana as the mother; in red the book with Morgause as Mordred's mother and dark blue for everything else.

Who is Mordred's mother? This is a list of ancient books I read and the parentage of Mordred.

HISTORIA BRITONUM: No Mordred.
ANNALE CAMBRIAE: There is Mordred/Medraut but there is nothing about his parents.
HISTORIA REGUM BRITANNIAE: Mordred è figlio di Anna e Lot. Poiché c'è Lot presuppongo che Anna sia Morgause anche perché Morgause è effettivamente conosciuta come Anna Morgause in altri testi. Inoltre Anna è sorella di Artù.
CHRETIEN DE TROYES: No Mordred. But we have a Morgana and no telling about her children.
CULHWICH AND OLWEN: Nothing of Mordred, Morgause or Morgana.
LANCELOT-GRAIL: I've read a modernization and Morgause was Mordred's mother. I'm not sure about his father.
ALLITERATIVE MORTE ARTHURE: Reading it : D I'll let you know.
MORTE d'ARTHUR: Mordred is the son of Morgause and Arthur

And now the modern books. In this color  the books with Morgana as the mother; in red the book with Morgause as Mordred's mother and dark blue for everything else.

Exiled from Camelot

Merlin and the book of Beasts (we know nothing of his mother)
The knights of the round table (1953) (Mordred is Morgana's husband)

22 recent/modern books with 14 Morgause (with one 'maybe'), 3 Other and 5 Morgana (with 2 'maybe').
And 10 film/telefilm with 3 Other, 1 Morgause and 6 Morgana.

And now we may see when those books were written.
The mists of avalon (1979)
Firelord (still not sure about Mordred's mother) (1980)
Knight Life (still not sure about Mordred's mother) (1987)

And the movies:
Excalibur (1981)
Connecticut Yankee (1989)
Doctor Who (1989)
Merlin (1998)
Merlin the return (2000)
Mists of Avalon (2001)

Every book and movie is after the publication of The Mists of Avalon.
Please, help me! Are there any other books/movies with Morgana as Mordred's mother before the 1979?
