On a recent BBC QI programme I was interested to learn that the robes seen on representations of the Buddha are actually influenced by ancient Greece. A quick bit of research confirmed this, and furthermore that much of Buddhist art throughout Asia has Hellenistic influences.
Following the conquests of Alexander the Great around 330 BC,
powerful Hellenistic states were set up in the area now known as Afghanistan and in Northern India. A fusion of Hellenistic and Buddhist elements started to appear in art, encouraged by the benevolence of the Greek kings towards Buddhism.
