Taishō Tripiṭaka
When the Chinese monk Faxian visited the island in the early 5th century, he noted 5000 monks at Abhayagiri, 3000 at the Mahāvihāra, and 2000 at the Cetiyapabbatavihāra. Faxian also obtained a Sanskrit copy of the Vinaya of the Mahīśāsaka at the Abhayagiri vihāra (c. 406). This was then translated into Chinese and remains extant in the Chinese Buddhist canon as Taishō Tripiṭaka 1421.
