Olympia, a sanctuary of ancient Greece in Elis, is known for having been the site of the Olympic Games in classical times. The Olympic Games were held every four years, dating back to 776 BC. In 394 AD, emperor Theodosius I abolished them as they were then considered reminiscent of paganism. The first Olympic Games were in honor of Zeus.
The Olympic flame of the modern-day Olympic Games is lit by reflection of sunlight in a parabolic mirror in front of the Temple of Hera and then transported by a torch to the place where the games are held. - in: wikipedia
