Explanation:

Greek actress Katerina Lehou, playing the role of high priestess, lights a torch from the sun's rays reflected in a parabolic mirror during a flame lighting ceremony at the site of ancient Olympia in Greece. Today, the Olympic flame is lit in front of the ruins of the Temple of Hera in Olympia, Greece. The flame emphasizes the connection between the ancient games and the modern ones. In the past, a high priestess of the Temple of Hera would light the flame using a skaphia, the ancestor of parabolic mirrors.
