An ancient assessment of Alexander
The translation was made by L. Jones.
Now, towards the end of his treatise -after withholding praise from those who divide the whole multitude of mankind into two groups, namely Greeks and Barbarians, and also from those who advised Alexander to treat the Greeks as friend but the Barbarians as enemies- Eratosthenes goes on to say that it would be better to make such divisions according to good and bad qualities; for not only are many of the Greeks bad, but many of the Barbarians are refined - Indians and Arians for example, and, further, Romans and Carthaginians, who carry on their governments so admirably.
And this, Eratosthenes says, is the reason why Alexander, disregarding his advisers, welcomed as many as he could of the men of fair repute an did them favors.
