In this Aug. 4, 2015 photo, “promesantes” or devotees, pour black recycled motor oil on their hands in order to cover themselves with it, during Managua’s patron saint, Santo Domingo de Guzman’s celebration, in Managua, Nicaragua. Devotees dress up as Indian chiefs and paint themselves as dancing red and black devils with the oil, as they invade the Nicaraguan capital each August during the festivities. (AP Photo/Esteban Felix)
