>>21072378>Merlin>the wizard>ArthurArthur is a bit of a slippery slope, although some Arthur could've existed at some point, he was greatly exaggerated, including the people around his time
Merlin for example could've just been a very well Roman educated court man who obeyed Arthur.
And the giant? Well, perhaps a massive brute of a worker.
The stone in sword? Dude some people in a tavern got black out drunk and probably made a dumbass game on who could pull out a sword out of the ground the fastest, and Arthur won by coincidence.
But the biggest flaw with the Arthurian tales is that they were mostly made the fuck up
