The city of Mechon (Mecca), where Mohammed is buried, is also in the great desert of Arabia. His body lies there very honourably in their temple, which the Saracens call mosque. It is from Babylon the Less, where the sultan dwells, to Mechon, about thirty-two days. The realm of Arabia is a very great country; but therein is over much desert, and no man may dwell there in that desert, for want of water, because the land is all gravelly and full of sand. And it is dry and entirely barren, because it hath no moisture, and therefore is there so much desert. And if it had rivers and wells, and the land were as in other parts, it would be as full of people and as well inhabited as in other places. For there is a great multitude of people wherever the land is inhabited. Arabia reaches from the borders of Chaldea to the extremity of Africa, and borders on the land of Idumea, towards the end of Botron. And in Chaldea the chief city is Baldak[307]. The chief city of Africa is Carthage, which Dido, who was Eneas's wife, founded. Mesopotamia stretches also unto the deserts of Arabia; it is an extensive country, and in it is the city of Haran, where Abraham's father dwelt, and from whence Abraham departed by command of the angel[308]. And of that city was Ephraem[309], who was a celebrated scholar. Theophilus was also of that city, whom our Lady saved from the evil one[310]. Mesopotamia reaches from the river Euphrates to the river Tigris, lying between those two rivers; and beyond the Tigris is Chaldea, which is a very extensive kingdom. In that realm, at Baldak abovesaid, the khalifs formerly dwelt, who were both as emperors and popes of the Arabians, lords spiritual and temporal. They were the successors of Mohammed, from whom they were descended. The city of Baldak was formerly called Sutis[311], and was founded by Nebuchadnezzar. There dwelt the holy prophet Daniel, and there he saw visions of heaven, and there he made the exposition of dreams[312]. There were formerly three khalifs, and they dwelt in the city of Baldak abovesaid.
