Hello hello! If you have the time/energy, I would LOVE to hear more on your view on Cersei as an Evil Queen retelling + Guinevere! Fascinated!
Hey @letters-to-theo!
I wanted to write a little about Jaime and Cersei and fairytale tropes/Arthurian for a while, so you've now given me the opportunity!
I think to begin with, GRRM intended ASOIAF partly as a play on Arthurian legend, particularly the story of Lancelot and Guinevere. In the legend, Guinevere is the wife of King Arthur, but engages in an affair with Lancelot, one of her husband's knights. In different versions of the story, different things happens to Guinevere and Lancelot, but in most versions they run away to a castle called "Joyous Gard" to be together (which translates into English as *drum roll*... Tower of Joy), and the fall out from their affair leads to a civil war and the downfall of the kingdom. In some versions, Guinevere is saved from execution for infidelity by Lancelot, and in others she returns to Arthur and he forgives her, but in all she is blamed for Camelot's fall due to her infidelity starting a chain of discord that led to the war. Lancelot's story is generally more streamlined: he fails to find the Holy Grail given his personal flaws that are exemplified by his relationship with Guinever, spends some time in exile away from Camelot, has a relationship with a woman called Elaine of Corbenic (who is in unrequited love with him) and has a son called Galahad with her, then after the fall of Camelot retires to a hermitage to atone for his sins and pin for Guinevere.
As you can probably tell, there are several characters in ASOIAF that take on aspects of Lancelot/Guinevere. Most obviously, Rhaegar and Lyanna fleeing to the "Tower of Joy" to conduct an illicit affair together screams Lancelot/Guinevere, with Robert playing Arthur. Robert then got to play Arthur *again* during his marriage to Cersei, as his wife was having an affair with one of his knights - Jaime - unbeknownst to him. Of course, Jaime and Cersei's affair leads to a huge civil war that leads to the ruin of the kingdom. Interestingly, in some versions of the Arthurian legends, Arthur unknowingly sleeps with his sister, Morgan le Fay, and the product of their incest - their son, Mordred - opposes his father in the upcoming civil war. Of course, this all screams Robert/Cersei/Jaime and Joffrey. Yet this is not the only version of Lancelot/Guinevere in ASOIAF. Cersei has an affair with her cousin, Lancel (get it?), and after their relationship ends he withdraws into religious life to atone for his sins. We therefore have different aspects of the Arthurian stories in all these characters.
Yet that is not where it stops. As you probably noticed, Lancelot's son with Elaine of Corbenic was called Galahad. Galahad becomes the Perfect Knight, whose virtue allows him to find the Holy Grail and do everything his father never could due to his own flaws. It is therefore not a coincidence that Brienne models herself after Galladon of Morne, and that the theme of legacy runs deep through Jaime's chapters. Is Brienne Jaime's Galahad? Or is she going to be the mother of his Galahad? That question can only be answered by future books.
As for Cersei and the Evil Queen in Snow White, there are *loads* of links (down to the level of silly jokes, as throughout AFFC, Cersei is instrumental in killing several dwarfs), but to prevent this post getting too long, I'll share this link which goes into the idea in some depth.
