So my book has a scene that recounts Arthur's pulling of the sword from the stone. Arthur is called Wart (a moniker T.H. White uses in his book The Once and Future King), and the scene isn't exactly as White's version, but it does closely resemble it (i.e., Kay forgets his sword at the inn, inn's closed, Wart finds the stone in front of a church). I did not read White's version of Arthur's rise to kingship until after I wrote the scene to avoid tainting my vision of what I wanted to present. I based the scene on what I'd already known prior. I've been researching the copyrights surrounding this with little to no results. Does anyone have any knowledge as to whether this infringes upon copyright?
