Olympic torch lit by sun's rays at birthplace of Games

The flame will make a 1,800-mile journey through Greece using 490 torchbearers.

The Associated Press reports — The flame that will burn during the London Games was lit at the birthplace of the ancient Olympics on Thursday, heralding the start of a torch relay that will culminate with the opening ceremony on July 27.

Actress Ino Menegaki, dressed as a high priestess, stood before the 2,600-year-old Temple of Hera, and after an invocation to Apollo, the ancient Greeks' Sun God, used a mirror to focus the sun's rays and light a torch.

The triangular torch is designed to highlight the fact that London is hosting the Olympics for the third time. It also staged the games in 1908 and 1948.

Under bright sunny skies there was no need for the backup flame that was used during the final rehearsal for the Olympic torch lighting a day earlier
