Legends can be thought of as embellished historical accounts that grow over time with each retelling - like those of Robin Hood or King Arthur. Legends have emerged in every place on the planet and during every era, even in recent history. In the U.S., sports legends come to mind.
I love this quote from the 1993 movie Sandlot in which the baseball legend, Babe Ruth, appears in a dream and says, "Remember kid, there's heroes and there's legends; heroes get remembered, but legends never die.”
An ancient legend that stole the imagination and hearts of many Americans, including mine, was that of King Arthur portrayed in Camelot on Broadway in 1960 and in the musical movie by that name released in 1967 - in part because of its association with a tragic historic U.S. event during that time.
