Last of all he came to the wine, and having learnt their way of making it, he drank a draught, which greatly delighted him; whereupon he asked what the Persian king was wont to eat, and to what age the longest-lived of the Persians had been known to attain. They told him that the king ate bread, and described the nature of wheat- adding that eighty years was the longest term of man’s life among the Persians. Hereat he remarked, “It did not surprise him, if they fed on dirt, that they died so soon; indeed he was sure they never would have lived so long as eighty years, except for the refreshment they got from that drink (meaning the wine), wherein he confessed the Persians surpassed the Ethiopians.”
The Icthyophagi then in their turn questioned the king concerning the term of life, and diet of his people, and were told that most of them lived to be a hundred and twenty years old, while some even went beyond that age- they ate boiled flesh, and had for their drink nothing but milk.
