Leon

Leon is a name of Greek origin. The Greek λέων (leōn), meaning "lion," has spawned the Latin "leo," French "lion," Irish "leon", Spanish "león," and Russian "lev." Perhaps the oldest attested historical figure to bear this name was Leon of Sparta, a 5th-century BC king, while in Greek mythology Leon was a Giant killed by Heracles. During the Christian era Leon was merged with the Latin cognate Leo, with the result that the two forms are used interchangeably. Other names based from the same root are Leonard, Leonid and Leonidas.

Leon is also the name of a number of geographical locations, including a province of Spain which played an important political and military role in the Middle Ages and Renaissance.
