Rome, July 19 - Police said Friday that they had found and seized 36 manuscripts by Italian writer Giovanni Verga in a special operation by a unit specialised in dealing with illegal possession and trade of cultural treasures. Hundreds of Verga's letters were also confiscated in Rome and the northern city of Pavia, along with notes and drawings by him. The material, which has an estimated value of four million euros, has been taken to the University of Pavia's manuscript research centre. Verga (1840-1922) was an Italian realist writer. He is famous for his portrayals of life in Sicily. His most famous works are the short story Cavalleria Rusticana, which was subsequently made into a play and an opera, and the novel I Malavoglia (The House by the Medlar Tree).
