Greco-Buddhist monasticism

The role of Greek Buddhist monks in the development of the Buddhist faith under the patronage of Emperor Ashoka around 260 BCE and subsequently during the reign of the Indo-Greek king Menander (r. 165/155–130 BCE) is described in the Mahavamsa, an important non-canonical Theravada Buddhist historical text compiled in Sri Lanka in the 6th century in the Pali language.
