According to Greek legend, the Olympic Games were started by Hercules, son of Zeus, in honour of his father. The first Olympic Games about which we have information were held in 776 BC on the plain of Olympia. Games had taken place before this date but had consisted mainly of chariot races. The ancient Greeks thought the Games were so important that they measured time by the interval between them. A period of four years was referred to as an Olympiad. The Games also represented the Greek ideal of physical fitness and beauty, which they considered as important as the development of the mind. Nothing, not even war, was allowed to interfere with the Games. They were held continuously every four years for more than 1000 years until the Romans brought them to an end in AD 394.
