The idea that the “original” Olympics in ancient Greece (which ran from 776 BC to AD 393) were only open to amateurs, void of cheating and corruption, free from commercialism, and a time of peace across Greece is just a myth. It didn’t exist in Greek mythology, though. The myth of an amateur Olympics is entirely a product of the late 19th century, when the idea of organized, regularly-scheduled games with international participation was conceived.
