Mahavamsa §29 records that during the rule of the Greco-Bactrian King Menander I, a Yona head monk named Mahadharmaraksita led 30,000 Buddhist monks from "the Greek city of Alasandra" (Alexandria in the Caucasus, around 150 kilometers north of modern Kabul, Afghanistan) to Sri Lanka for the dedication of the Ruwanwelisaya in Anuradhapura, indicating that Greco-Buddhism contributed to early Sri Lankan Buddhism.
