Thousands of believers dressed in purple congregate to pay homage to Peru's most revered Catholic religious icon, "the Lord of the Miracles", in a major procession through central Lima October 18, 2009. The procession - which gathers the largest number of believers in South America - dates back to colonial times, when a slave, brought over from Angola, drew the image of a black Christ on the walls of a hut in the plantation of Pachacamilla, near Lima.
