TO Herodotus of Halicarnassus, greeting.—Concerning the matters set forth in your histories, and the tales you tell about both Greeks and Barbarians, whether they be true, or whether they be false, men dispute not little but a great deal. Wherefore I, being concerned to know the verity, did set forth to make search in every manner, and came in my quest even unto the ends of the earth. For there is an island of the Cimmerians beyond the Straits of Heracles, some three days’ voyage to a ship that hath a fair following wind in her sails; and there it is said that men know many things from of old: thither, then, I came in my inquiry. Now, the island is not small, but large, greater than the whole of Hellas; and they call it Britain. In that island the east wind blows for ten parts of the year, and the people know not how to cover themselves from the cold. But for the other two months of the year the sun shines fiercely, so that some of them die thereof, and others die of the frozen mixed drinks; for they have ice even in the summer, and this ice they put to their liquor. Through the whole of this island, from the west even to the east, there flows a river called Thames: a great river and a laborious, but not to be likened to the River of Egypt. The mouth of this river, where I stepped out from my ship, is exceedingly foul and of an evil savour by reason of the city on the banks. Now this city is several hundred parasangs in circumference. Yet a man that needed not to breathe the air might go round it in one hour, in chariots that run under the earth; and these chariots are drawn by creatures that breathe smoke and sulphur, such as Orpheus mentions in his “Argonautica,” if it be by Orpheus. The people of the town, when I inquired of them concerning Herodotus of Halicarnassus, looked on me with amazement, and went straightway about their business—namely, to seek out whatsoever new thing is coming to pass all over the whole inhabited world, and as for things old, they take no keep of them. Nevertheless, by diligence I learned that he who in this land knew most concerning Herodotus was a priest, and dwelt in the priests’ city on the river which is called the City of the Ford of the Ox. But whether Io, when she wore a cow’s shape, had passed by that way in her wanderings, and thence comes the name of that city, I could not (though I asked all men I met) learn aught with certainty. But to me, considering this, it seemed that Io must have come thither. And now farewell to Io.
