There is more to be said about these settlements later. The first actual record of settlement of Greeks in Baktria is that of Herodotus, to which we have referred as being affected by Darius Hystaspes in the sixth century before Christ, and the descendants of these settlers are undoubtedly the people referred to by Arrian as "Kyreneans", who could be no other than the Greek captives from the Lybian Barke. Their existence two centuries later than Herodotus is attested by Arrian, and they were apparently in possession of the Kaoshan pass over the Hindu Kush at the time of Alexander's expedition. Another body of Greeks is recorded by Arrian to have been settled in the Baktrian country by Xerxes after his flight from Greece. These were the Brankhidai of Milesia, whose posterity are said to have been exterminated by Alexander in punishment for the crimes of their grandfather Didymus. The name Barang, or Farang, is frequently repeated in the mountain districts of Northern Afghanistan and Badakshan, and careful inquiry would no doubt reveal the fact that surviving Greek affinities are still far more widely spread through that part of Asia than is generally known. All these settlements were antecedent to Alexander, but beyond these recorded instances of Greek occupation there can be little doubt that (as pointed out by Bellew in his _Ethnography of Afghanistan_ and supported by later observations) the Greek element had been diffused through the wide extent of the Persian sovereignty for centuries before the birth of Alexander the Great. It is probable that each of the four great divisions of the ancient Greeks had contributed for a thousand years before to the establishment of colonies in Asia Minor, and from these colonies bands of emigrants had penetrated to the far east of the Persian dominions, either as free men or captives. Amongst the clans and tribal sections of Afghans and Pathans are to be found to this day names that are clearly indicative of this pre-historic Greek connection.
