Ancient Gandhara in the upper Indus valley is where a Hellenistic culture turn Buddhist. Source
Session 4 of Reading Plato comes to the Phaedo’s myth of the soul’s transmigration, where students are often astonished by the similarities with Buddhist doctrine. This raises the question of whether Platonism influenced Buddhism, or whether Plato and Buddhism share a common source.
This question has been raised many times down through the centuries and continues to be asked by modern scholars. Much of the interest centres around the ancient Gandharan civilisation of the northern Indus valley in modern day Pakistan. Gandhara was part of the great Persian Empire until Alexander’s conquest, when it came under Hellenistic influence in its art and culture. But then it turned to Buddhism.
