Many other isles[414] there are in the land of Prester John, and many great marvels, that were too long to tell, both of his riches and of his nobleness, and of the great plenty also of precious stones that he has. I think that you know well now, and have heard say, why this emperor is called Prester John. There was some time an emperor there, who was a worthy and a full noble prince, that had Christian knights in his company, as he has that now is. So it befell that he had great desire to see the service in the church among Christians; and then Christendom extended beyond the sea, including all Turkey, Syria, Tartary, Jerusalem, Palestine, Arabia, Aleppo, and all the land of Egypt. So it befell that this emperor came, with a Christian knight with him, into a church in Egypt; and it was the Saturday in Whitsuntide. And the bishop was conferring orders; and he beheld and listened to the service full attentively; and he asked the Christian knight what men of degree they should be that the prelate had before him; and the knight answered and said that they were priests. And then the emperor said that he would no longer be called king nor emperor, but priest; and that he would have the name of the first priest that went out of the church; and his name was John. And so, evermore since, he is called Prester John. CHAPTER XXX. OF THE HILLS OF GOLD THAT ANTS KEEP; AND OF THE FOUR STREAMS THAT COME FROM TERRESTRIAL PARADISE. Towards the east of Prester John's land is a good and great isle called Taprobane, and it is very fruitful; and the king thereof is rich, and is under the obeisance of Prester John. And there they always make their king by election. In that isle are two summers and two winters; and men harvest the corn twice a year; and in all seasons of the year the gardens are in flower. There dwell good people, and reasonable; and many Christian men among them, who are so rich that they know not what to do with their goods. Of old time, when men passed from the land of Prester John unto that isle, men made ordinance to pass by ship in twenty-three days or more; but now men pass by ship in seven days. And men may see the bottom of the sea in many places; for it is not very deep. Beside that isle, towards the east, are two other isles, one called Orille, the other Argyte, of which all the land is mines of gold and silver. And those isles are just where the Red Sea separates from the Ocean Sea. And in those isles men see no stars so clearly as in other places; for there appears only one clear star called Canopus. And there the moon is not seen in all the lunation, except in the second quarter. In the isle, also, of this Taprobane are great hills of gold, that ants keep full diligently[415].
