In Pictures: Spain's annual grease-filled Cascamorras festival

People cover themselves with thick, black grease as they take part in the annual Cascamorras festival in Baza, Spain. The festival that takes place in September was inspired by a dispute between the town of Baza and Guadix over the possession of an icon of the Virgin of Piedad over 500 years ago. The Cascamorras refer to representatives from Guadix, who were sent to Baza to recover the statue. As the Cascamorras had to stay perfectly clean to gain possession of the statue, Baza residents attempt to make them as "dirty" as possible.
