Thank you @papi.mati! This story about penetration of the Greek culture into South Asia shows how much things were interconnected - not like today of course :D but the civilisations were linked. I heard talks for example that Jesus could travel to India. No proofs... But it could be, who knows.
There was regular sea trade between the Middle East and India since early times, this is how Christianity arrived in Kerala (India) earlier than in some European regions.
