The Mahavamsa, chapter 29, records that during Menander's reign, a Greek thera (elder monk) named Mahadharmaraksita led 30,000 Buddhist monks from "the Greek city of Alexandria" (possibly Alexandria on the Caucasus, around 150 kilometers north of today's Kabul in Afghanistan), to Sri Lanka for the dedication of a stupa, indicating that Buddhism flourished in Menander's territory and that Greeks took a very active part in it.
