SANTIAGO, Chile (AP) — Nicanor Parra, a Chilean physicist, mathematician and self-described "anti-poet" whose eccentric writings won him a leading place in Latin American literature, died Tuesday. He was 103. His death was confirmed by Chilean President Michelle Bachelet, who expressed her condolences. Her government ordered national flags to be flown at half-staff in public buildings and decreed two days of mourning. "Chile loses one of the greatest authors in the history of our literature and a singular voice in Western culture," she said.
