ON Sunday, May 24, 2015, red rose petals will cascade through the oculus of Hadrian's Pantheon in Rome.
The event commemorates the ancient Roman spring festival as well as Christian Pentecost.
Rome firefighters scaled the 43-meter-high dome to pour the rose petals through the 9-meter-wide oculus "eye opening" at the top of the historic building.
The ceremony, suspended for many years, was revived in 1995. It dates back to the earliest days of Christianity when the falling rose petals symbolized flames of Pentecostal enlightenment showering down on the faithful.
