Things got macabre in Luzon, a village in Guadalajara, Spain on Sunday when people painted their faces and donned costumes for the annual “Diablos de Luzon” (Luzon’s Devils) carnival. /VCG Photo

Wearing black face paint and horns, the “devils” are villagers possessed by evil spirits that emerge once a year, according to local folklore. Their counterparts, the “masks,” wear white masks and traditional women’s clothing, and are immune to possession. /VCG Photo

The festival is believed to date from Celtic times. /VCG Photo
