There is some debate regarding the exact date for the development of the anthropomorphic representation of the Buddha, and this has a bearing on whether the innovation came directly from the Indo-Greeks, or was a later development by the Indo-Scythians, the Indo-Parthians or the Kushans under Hellenistic artistic influence. Most of the early images of the Buddha (especially those of the standing Buddha) are anepigraphic, which makes it difficult to have a definite dating. The earliest known image of the Buddha with approximate indications on date is the Bimaran casket, which has been found buried with coins of the Indo-Scythian king Azes II (or possibly Azes I), indicating a 30–10 BC date, although this date is not undisputed.
