At that time, when Hellestheaeus was reigning over the Aethiopians, and Esimiphaeus over the Homeritae, the Emperor Justinian sent an ambassador, Julianus, demanding that both nations on account of their community of religion should make common cause with the Romans in the war against the Persians; for he purposed that the Aethiopians, by purchasing silk from India and selling it among the Romans, might themselves gain much money, while causing the Romans to profit in only one way, namely, that they be no longer compelled to pay over their money to their enemy. (This is the silk of which they are accustomed to make the garments which of old the Greeks called Medic, but which at the present time they name “seric"[28]). As for the Homeritae, it was desired that they should establish Caisus, the fugitive, as captain over the Maddeni, and with a great army of their own people and of the Maddene Saracens make an invasion into the land of the Persians. This Caisus was by birth of the captain’s rank and an exceptionally able warrior, but he had killed one of the relatives of Esimiphaeus and was a fugitive in a land which is utterly destitute of human habitation. So each king, promising to put this demand into effect, dismissed the ambassador, but neither one of them did the things agreed upon by them. For it was impossible for the Aethiopians to buy silk from the Indians, for the Persian merchants always locate themselves at the very harbours where the Indian ships first put in, (since they inhabit the adjoining country), and are accustomed to buy the whole cargoes; and it seemed to the Homeritae a difficult thing to cross a country which was a desert and which extended so far that a long time was required for the journey across it, and then to go against a people much more warlike than themselves. Later on Abramus too, when at length he had established his power most securely, promised the Emperor Justinian many times to invade the land of Persia, but only once began the journey and then straightway turned back. Such then were the relations which the Romans had with the Aethiopians and the Homeritae.
