Of the Yavana princes who ruled only to the south of the Hindu Kush, Apollodotus would seem to have been the first. He is twice mentioned by ancient authors, and on both occasions in association with Menander. From such evidence as is forthcoming we may reasonably conclude that the two princes were members of the family of Euthydemus, that they belong to the same period—the period of Yavana expansion—and that Apollodotus was the elder.
