The French Perceforest presents the famed Macedonian king (356-323 BC) as an ancestor of Arthur. A storm drove him to Britain, where he quelled the war-torn island and established secure rulers. He loved Sebille, then the Lady of the Lake.
Alexander is only one of many historical and legendary people connected to the Arthurian cycle in various texts. The association was to be expected, given the similarities between the legend of Alexander and the myth of Arthur: both were historical figures to whom fabulous legends were attached; both grew up away from the royal court; both became rulers following the assassinations of their fathers; both endured a period of rebellion before securing the throne; both experienced problems with neighboring barbarians; both conquered most of the known world; both were deified by their countrymen; both had their thrones usurped while leading military expeditions in foreign lands; both were rumored to have died; both returned to their homelands and killed the rebels; both left their countries in anarchy after their deaths; and, finally, both were said to be living in otherwordly kingdoms.
