The original Olympics looked almost nothing like the modern ones, but we like to draw on the ancient origins and so we still hold a ceremony at their birthplace: Olympia, Greece. Like children igniting ants with a magnifying glass, the actresses who play the part of Greek priestesses light the initial Olympic torch with a mirror. Specifically, they use a parabolic mirror, which is a curved and looks a bit like a small satellite dish. The curvature focuses light in one spot, called a focal point, where the beams all meet at a single, intense spot. The one used in the ceremony at the Temple of Hera in Olympia has a focal point just above the mirror's surface. A "priestess" simply has to hold the torch in that spot and wait for the light to heat the fuel enough for it to ignite.
