An actress dressed as a high priestess of ancient Greece Tuesday lit the Olympic flame that will be carried to Seoul, South Korea, for the 1988 Summer Games beginning Sept. 17.

Katerina Didaskalou, dressed in white robes, knelt on one knee and held a torch to a concave mirror that focused the sun's rays to ignite the flame.The ceremony at the sanctury of the god Zeus in ancient Olympia, some 112 miles southwest of Athens, was attended by about 15,000 people, witnesses said.
