This literature includes the work of prominent scholars such as Anuruddha, Sumangala, Siddhattha, Sāriputta Thera, Mahākassapa of Dimbulagala and Moggallana Thera. They worked on compiling subcommentaries to the Tipitaka, grammars, summaries and textbooks on Abhidhamma and Vinaya such as the influential "Abhidhammattha-sangaha" of Anuruddha. They also wrote "kavya" style Pali poetry and philological works. Their work owed much to the influence of Sanskrit grammar and poetics, particularly as interpreted by the Sri Lankan scholar Ratnamati. During this period, these new Pali doctrinal works also show an increasing awareness of topics found in Sanskrit Buddhist Mahayana literature.
