Rome, September 9 - Popular Italian writer Alberto Bevilacqua died after a long illness aged 79 on Monday. Bevilacqua was a highly prolific author who produced over 40 books between the early 1960s until last year that helped tell the story of life in Italy after World War II. His breakthrough novel was Caliph, published in 1964. Two years later he won one of Italy's top literary awards, the Campiello Prize, for This Kind of Love. He also directed and wrote the screenplays for several movies, including the successful film adaptations of Caliph and This Kind of Love. He published several collections of poems too. Some of his works were translated into foreign languages and published in other parts of Europe, North and South America and Asia. Bevilacqua died at a Rome clinic that was subject to a legal wrangle, after his partner complained after the treatment he received. Rome prosecutors are investigating the case.
