Revellers put grease on their bodies as they take part in the annual Cascamorras festival in Baza, southern Spain September 6, 2018. The festival was inspired by a dispute between the town of Baza and Guadix over the possession of an icon of the Virgin of Piedad. The Cascamorras refers 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.
