The Third Kalandar’s Tale.

The fable is probably based on the currents which, as in Eastern Africa, will carry a ship fifty miles a day out of her course. We first find it in Ptolemy (vii. 2) whose Maniólai Islands, of India extra Gangem, cause iron nails to fly out of ships, the effect of the Lapis Herculeus (Loadstone). Rabelais (v. c. 37) alludes to it and to the vulgar idea of magnetism being counteracted by Skordon (Scordon or garlic). Hence too the Adamant (Loadstone) Mountains of Mandeville (chapt. xxvii.) and the "Magnetic Rock" in Mr Puttock's clever "Peter Wilkins." I presume that the myth also arose from seeing craft built, as on the East African Coast, without iron nails. We shall meet with the legend again. The word Jabal ("Jebel" in Egypt) often occurs in these pages. The Arabs apply it to any rising ground or heap of rocks; so it is not always = our mountain. It has found its way to Europe e. g. Gibraltar and Monte Gibello (or Mongibel in poetry) "Mt. Ethne that men clepen Mounte Gybelle." Other special senses of Jabal will occur.
