As the advisor who helps King Arthur through the early years of his reign, Merlin has become the most famous wizard of all time.
The stories of Merlin may have been based on a real person. But the character we know as Merlin today has come down to us through the “History of the Kings of Britain”, a book by the twelfth-century English writer Geoffrey of Monmouth. A later text called “Le Morte D’Arthur”, written by fifteenth-century English writer Thomas Malory, further popularised the tale of this wizard.
In most sources since these two original tales, the story of Merlin begins with a king called Vortigern. Vortigern wanted to build a tower in his kingdom. But whenever he tried to build one, the tower would crumble.
