104. For the people of Colchis are evidently Egyptian, and this I perceived for myself before I heard it from others. So when I had come to consider the matter I asked them both; and the Colchians had remembrance of the Egyptians more than the Egyptians of the Colchians; but the Egyptians said they believed that the Colchians were a portion of the army of Sesostris. That this was so I conjectured myself not only because they are dark-skinned and have curly hair (this of itself amounts to nothing, for there are other races which are so), but also still more because the Colchians, Egyptians, and Ethiopians alone of all the races of men have practised circumcision from the first. The Phoenicians and the Syrians who dwell in Palestine confess themselves that they have learnt it from the Egyptians, and the Syrians about the river Thermodon and the river Parthenios, and the Macronians, who are their neighbours, say that they have learnt it lately from the Colchians. These are the only races of men who practise circumcision, and these evidently practise it in the same manner as the Egyptians. Of the Egyptians themselves however and the Ethiopians, I am not able to say which learnt from the other, for undoubtedly it is a most ancient custom; but that the other nations learnt it by intercourse with the Egyptians, this among others is to me a strong proof, namely that those of the Phoenicians who have intercourse with Hellas cease to follow the example of the Egyptians in this matter, and do not circumcise their children.
– Herodotus, Book II
Herodotus made his living by being interesting. In a world where most people did not read and could not afford to buy a book even if they could, they would pay to listen to Herodotus recite from his books. They would not pay to be bored. In that world, the names that populate his stories would have some general familiarity to his audience. Their obscurity to us is a barrier that this series seeks to break down.
