Sri Lanka
Sri Lanka became the headquarters of Theravada for centuries, and most Pali literature in this period was written there, though some was also produced in outposts in south India. After a gap following the completion of the canon in which little or no Pali literature was produced, it restarted with the Dipavamsa, a verse chronicle of Buddhism in India and Ceylon, followed by a similar, but longer, work, the Mahavamsa. An important text is Buddhaghosa's Visuddhimagga, which came to be regarded as the standard summary of the traditional interpretation of the scriptures, in the fourth or fifth century. Buddhaghosa also compiled commentaries on much of the Canon, work continued by his successors, who also produced subcommentaries on many commentaries, and sometimes even sub-subcommentaries. There were also handbooks summarizing some aspects of the teachings, and other literature, all or nearly all concerned with Buddhism, at least ostensibly. From the early thirteenth century the writing of Pali literature in Sri Lanka went into a steep decline, though it never ceased entirely. Instead, Buddhist literature was written in Sinhalese.
