How much poorer would European literature be if he didn't exist: MERLIN (according to Wikipedia, the Welsh name originates from Myrddin or Merddin) is one of the biggest stars in the sky of mythology. Together with the heroic King Arthur, he has conquered a permanent place in the collective memory of people - at least in the fantasy world of countless authors who have told his story over and over again for centuries, and above all in their ever-fascinating readers or listeners. I don't know what historical connection this hiking highlight, known as the "Siège de Merlin", has with the person of the legendary magician. But the main thing is: the myth lives on!
