The associations of the Buddhist revival also contributed much to the publication of Buddhist literature, and promotion of Buddhist scholarship. Revivalist Buddhist scholars include Sir D. B. Jayatilaka, F. R. Senanayake, Walisinghe Harischandra and W. A. de Silva. During the revivial, journalism was a major arena for religious discussion and debate. English as well as Sinhala were used in this new journalism. The works of the novelists Piyadasa Sirisena and Martin Wickramasinghe are examples of the Buddhist nationalist influenced literature of the 20th century.
