Greco-Buddhist art is the artistic manifestation of Greco-Buddhism, a cultural syncretism between the Classical Greek culture and Buddhism, which developed over a period of close to 1000 years in Central Asia, between the conquests of Alexander the Great in the 4th century BCE, and the Islamic conquests of the 7th century CE. Greco-Buddhist art is characterized by the strong idealistic realism of Hellenistic art and the first representations of the Buddha in human form, which have helped define the artistic (and particularly, sculptural) canon for Buddhist art throughout the Asian continent up to the present. Though dating is uncertain, it appears that strongly Hellenistic styles lingered in the East for several centuries after they had declined around the Mediterranean, as late as the 5th century CE. Some aspects of Greek art were adopted while others did not spread beyond the Greco-Buddhist area; in particular the standing figure, often with a relaxed pose and one leg flexed, and the flying cupids or victories, who became popular across Asia as apsaras. Greek foliage decoration was also influential, with Indian versions of the Corinthian capital appearing.
