About the photo: Flames burn in the Olympic cauldron after being lit during the opening ceremony of the 2016 Summer Olympics in Rio de Janeiro, Brazil on Saturday August 6, 2016.
The Associated Press has covered all of the modern Olympics, and that includes photographs of the Olympic flame both along the torch relay route and in the cauldron.
The Olympic Torch was introduced at the 1928 Amsterdam Olympics. The Torch Relay began eight years later before the 1936 Games in Berlin.
The flame begins its life during a lighting ceremony in ancient Olympia, where the first Olympic Games were held for centuries.
Over the years, the torch has played an increasingly important role in the Opening Ceremony, with the identity of the last torchbearer – often former Olympics from the host country – being the subject of heated debate. .
Muhammad Ali, a gold medalist at the Olympic Games in Rome in 1960, lit the torch for the Atlanta Games in 1996. Four years later, Cathy Freeman lit the flame in Sydney and became the only person to light a cauldron and to win a gold medal in the same games.
One of the most memorable lightings came at the Barcelona Olympics in 1992 when Paralympic archer Antonio Rebollo fired a flaming arrow above the cauldron, igniting gases from within.
The torch relay for the postponed Tokyo Games began on Thursday, but don’t expect to know the name of the person who lit the cauldron on July 23 during the opening ceremony anytime soon.
And when it does, the PA will be there to document it.
