The Olympics are not only about games, they are about discovery and creation of spectacular moments. There are athletes who have graced the Olympic stage with their presence and left a mark that cannot be replaced.
Muhammad Ali, Atlanta 1996
The lighting of the Olympic flame is a special moment at every Olympic Games, but Muhammad Ali's is one of the most touching.
It came nearly 40 years after he won gold in boxing. The world held their breath as he held the torch with shaking hands as a result of Parkinson's disease.
It came as a reminder that not even illness can stop the world's greatest athletes.
