Catholics and conservatives have denounced as blasphemous two recent exhibitions in Madrid featuring kinky nuns in lingerie and tattooed and near-naked Christs, demonstrating outside one gallery. Catholic group AES called a demonstration for Friday evening outside the Fresh Gallery in Madrid against its latest exhibition: "Obscenity", a collection of photographs by Canadian artist Bruce LaBruce. The 50 pictures on display include a portrait of Spanish actress Rossy de Palma in a black and white habit and see-through corset with a rosary between her teeth. One shows a well-known singer, Alaska, dressed as a sexy saint with a communion wafer on her tongue, while in another she hugs a tattooed Christ to her breast in a kinky tribute to Michaelangelo's Pieta sculpture. Around 50 protesters demonstrated outside the Fresh gallery Friday evening bearing placards reading "For a unified and Catholic Spain" and "God Exists". LaBruce himself was unrepentant. "How can fascists attempt to assert any sort of moral authority over anything?" he said. LaBruce, 48, whose work has often sparked protests and censorship, wrote on the gallery's website that "the lives of the saints are full of ecstatic acts of sublimated sexuality."
