“The stone magnet is believed by many to owe its name to Magnesia....” We consider, however, the opinion of the Hermetists to be the correct one. The word _magh_, _magus_, is derived from the Sanscrit _mahaji_, meaning the great or wise ... so the magnet stone was called in honour of the Magi, who were the first to discover its wonderful properties. Their places of worship were located throughout the country in all directions, and among these were some temples of Hercules, hence the stone--when it became known that the priests used it for their curative and magical purposes--received the name of Magnesian or Herculean stone. Socrates, speaking of it, says: “Euripides calls it the Magnesian stone, but the common people the Herculean” (Plato, “Ion”--Burgess--Vol. IV. p. 294). In the same Vol. I. of “Isis Unveiled” we are likewise informed that Electricity in the Norse legends is personated by Thor, the son of Odin, at Samothrace by the Kabeirian Demeter (Joseph Ennemoser, “History of Magic,” London, 1854, Vol. II.; J. S. C. Schweigger, “Introd. to Mythol. through Nat Hist.,” Halle, 1836), and that it is denoted by the “twin brothers,” the Dioskuri. Also that the _celestial_, pure fire of the Pagan altar was electrically drawn from the astral light, that magnetic currents develop themselves into electricity upon their exit from the body, and that the first inhabitants of the earth brought down the heavenly fire to their altars (J. S. C. Schweigger in Ennemoser’s “Hist. of Magic,” Vol. II. p. 30; Maurus Honoratus Servius, “Virgil,” Eclog. VI. v. 42). =B.C. 321.=--Theophrastus, Greek philosopher, first observed the attractive property of the _lyncurium_, supposed by many to be the _tourmaline_, and gave a description of it in his treatise upon stones (“De Lapidibus,” sec. 53; or the translation of Sir John Hill, 1774, chap. xlix.-l., p. 123). This crystal was termed _lapis lyncurius_ by Pliny in his “Nat. Hist.,” and _lapis electricus_ by Linnæus in his “Flora Zeylanica” (U. Aldrovandus, “Mus. Metal.”; Philemon Holland, “The Historie of the World,” commonly called “The Naturall Historie of C. Plinius Secundus,” London, 1601).
