In Pictures: St Peter's Basilica lights up for the environment

Images of clouds, lions and butterflies - alternating with polluted air and parched farmland - were projected on the famous facade of St Peter’s Basilica at the Vatican on Tuesday (Dec 8) night as global leaders try to thrash out a historic climate deal in Paris. The light show, titled Fiat Lux (Let There Be Light): Illuminating Our Common Home, also coincided with the festive launch on Tuesday of a special Catholic Jubilee Year on the theme of mercy. Thousands of people thronged St Peter’s Square for the hour-long light show featuring the work of some of the world’s best photographers including Sebastiao Salgado of Brazil, Joel Sartore of the United States and Frenchman Yann Arthus Bertrand. The images were accompanied not by music but by the sounds of nature such as stormy weather, birdsong and long stretches of silence. The initiative, backed by the World Bank, aims to underscore the Catholic Church’s push for environmental protection.
