Dress rehearsal for the Olympic flame lighting ceremony

During the rehearsal, a dozen young women in long, pleated robes, escorted by a dozen male youths, danced to the rhythm of a drum and the sound of a flute, according to ancient Greek tradition.

Greek actress Katerina Lehou , playing the role of High Priestess, is to light a torch from the sun's rays reflected in a parabolic mirror during the dress rehearsal for the Olympic flame lighting ceremony for the Rio 2016 Olympic Games at the site of ancient Olympia in Greece, April 20, 2016.

The torch will arrive in Brazil on May 3 for a 100-day relay across the country, traveling through 500 cities and villages in every Brazilian state and borne by some 12,000 torch bearers before arriving for the opening ceremony in Rio on Aug. 5 for the first Games in South America.
