PREFACE.
WE are entring upon a Subject which I confesse, is in it self harsh, and exotick, very un∣proper for our Tongue; yet I doubt not but they will pardon this, who shall consider, that other Philosophies and Sciences have been lately well received by several Nations translated into their own Languages; and that this, as being the first, contributes not a little to the understanding of the rest.
Another disadvantage this Subject incurres far more considerable: There is not any thing more difficult to be re∣triv'd out of the Ruins of Antiquity than the Learning of the Eastern Nations, and particularly that of the Chal∣daeans. What remains of it is chiefly transmitted to us by the Greeks, of whom, some converted it to their own use, in∣termixing it with their Philosophy, as Pythagoras and Pla∣to; others treated expressely of it, but their Writings are lost. Of its first Authors nothing remains; what others took from it, is not distinguishable from their proper Phi∣losophy. The Greeks were first made acquainted with it by Osthanes, and, long after, by Berosus, the former living in the time of Xerxes, the other, under Ptolomaeus Phila∣delphus. Whence it may be inferr'd, that the Discourse, which Democritus writ of Chaldaea, and his Commenta∣ry, of the Sacred Letters at Babylon, either came short of these Sciences, or were so obscure, that they conduced little to their discovery. Neither seems the Treatise, entituled Magi∣cum, ascribed, by some, to Aristotle, by others, to Rhodon, but indeed written by Antisthenes, to have considered the Learning and Sciences, so much as the History of the Profes∣sors. Of which kind were also the Writers concerning the Magi, cited, under that general Title, by Diogenes La∣ertius.
