After men have crossed this desert on the way to Jerusalem, they come to a city which is called Bersabee [Beersheba] which was once a fine city in habited by Christian men, and still there are some of their churches standing. In that city Abraham the Patriarch lived. Bersabee the wife of Ury [Uriah] founded that city, and called it Bersabee after herself. In that city King David begat on her Solomon the Wise, who was king of Jerusalem for 40 years.
(The Travels of Sir John Mandeville, Chapter Nine, translated by C. W. R. D. Mosely)
Sir John Mandeville here claims that the city of Beersheba was founded by Bathsheba yet a mere sentence earlier he states that Abraham lived there, and Abraham predates Bathsheba by several centuries. In fact, the Bible (Genesis 21:31) explicitly states that Abraham gave it the name Beersheba.
What are we to make of Sir John Mandeville's account? Is this simply a mistake (or deliberate distortion)? Is there, perhaps, an alternative chronology that places Bathsheba before Abraham? Is the naming of this city after Bathsheba attested to anywhere else?
(I am aware that the work as a whole is not considered entirely accurate, but I seek an explanation for this particular claim.)
