Olympic Torch:
"The Olympic Torch today is ignited several months before the opening ceremony of theOlympic Games at the site of the ancient Olympic in Olympia, Greece. Eleven women, representing the Vestal Virgins,[notes 1] perform a ceremony in which the torch is kindled by the light of the Sun, its rays concentrated by a parabolic mirror. The torch briefly travels around Greece via short relay, and is then transferred to the host city at a ceremony in the Panathinaiko Stadium in Athens.[3] The Olympic Torch Relay ends on the day of the opening ceremony in the central stadium of the Games. The final carrier is often kept unannounced until the last moment, and is usually a sports celebrity of the host country. The final bearer of the torch runs towards the cauldron, often placed at the top of a grand staircase, and then uses the torch to start the flame in the stadium. It is considered a great honor to be asked to light the Olympic Flame. After being lit, the flame continues to burn throughout the Games, and is extinguished on the day of the closing ceremony."

Olympic Rings:
"The emblem chosen to illustrate and represent the world Congress of 1914...: five intertwined rings in different colours - blue, yellow, black, green, and red - are placed on the white field of the paper. These five rings represent the five parts of the world which now are won over to Olympism and willing to accept healthy competition. Blue stands for Europe, black for Africa, Red for Americas, Yellow for Asia and, green for Oceania."
