writers into two classes, viz., the old lost Arabians, and the present. The former were very numerous, and divided into several tribes, which are now all destroyed, or else lost and swallowed up among the other tribes, nor are any certain memoirs or records extant concerning them;6 though the memory of some very remarkable events and the catastrophe of some tribes have been preserved by tradition, and since confirmed by the authority of the Korân. The most famous tribes amongst these ancient Arabians were Ad, Thamûd, Tasm, Jadîs, the former Jorham, and Amalek. 6 Sharif al Edrisi ubi supra, 125. 7 Id. Vulgò Geogr. Nubiensis, 5. 1 Though the notion of Mohammed's being buried at Mecca has been so long exploded, yet several modern writers, whether through ignorance or negligence I will not determine, have fallen into it. It shall here take notice only of two; one is Dr. Smith, who having lived some time in Turkey, seems to be inexcusable: that gentleman in his Epistles de Moribus ac Institutis Turcarum, no less than thrice mentions the Mohammedans visiting the tomb of their prophet at Mecca, and once his being born at Medina-the reverse of which is true (see Ep. I, p. 22, Ep. 2, p. 63 and 64). The other is the publisher of the last edition of Sir J. Mandevile's Travels, who on his author's saying very truly (p. 50) that the said tomb was at Methone, i.e., Medina, undertakes to correct the name of the town, which is something corrupted, by putting at the bottom of the page, Mecca. The Abbot de Vertot, in his History of the Order of Malta (vol. i. p. 410, ed. 8vo.), seems also to have confounded these two cities together, though he had before mentioned Mohammed's sepulchre at Medina. However, he is certainly mistaken, when he says that one point of the religion, both of the Christians and Mohammedans, was to visit, at least once in their lives, the tomb of the author of their respective faith. Whatever may be the opinion of some Christians, I am well assured the Mohammedans think themselves under no manner of obligation in that respect. 2 Gol. ad Alfragan. 97, Abulfeda Descr.
