I was at the National gallery of Victoria in Melbourne yesterday, and paused to look at some statues of Buddha and various Bodhisattva that looked decidedly Greek in terms of their flowing, toga like robes, the realistic treatment of their bodies, facial features and hair. As confimred by the commentary next to these, they show a Hellenistic influence due to the invasion of Gandhara by Alexander. (Gandhara somewhere around southern Afganistan/Northern India/Pakistan).
It was something I hadn't come accross before, so thought I'd post this link to gandhara.com.au where there is a Gallery of similar statues/heads etc from the same area. They were sculpting Hellenic mythological figures prior to or perhaps at the same time as the Buddha images - on this website I found a partial sculpture of Atlas from the same period. Makes it all the worse in my mind that it's just this kind of thing the Taliban were destroying prior to invasion.
