Note 27 — Chapter III · THAT PRESCIENCE IS USEFUL

J. M. Ashmand translation

Respecting the effect here asserted to be produced on the magnet by garlick, I have found the following mention in a book called “The Gardener’s Labyrinth,” printed at London in 1586. “Here also I thought not to ouerpasse the maruellous discord of the adamant-stone and garlike, which the Greeks name to be an Antipatheia or naturall contrarietie betweene them; for such is the hatred or contrarietie between these two bodies (lacking both hearing and feeling), that the adamant rather putteth away, than draweth to it, iron, if the same afore be rubbed with garlike; as Plutarchus hath noted, and, after him, Claudius Ptolemæus. Which matter, examined by divers learned, and founde the contrarie, caused them to judge, that those skilful men (especially Ptolemie) ment the same to be done with the Egyptian Garlike; which Dioscorides wrote to be small garlike, and the same sweete in taste, possessing a bewtifull head, tending unto a purple colour. There be which attribute the same to Ophioscoridon, which Antonius Microphonius Biturix, a singular learned man, and wel practised in sundry skilles, uttered this approoued secrete to a friend whom he loued.”

In the same book, the “Ophioscoridon” is thus spoken of: “There is another wild garlike which the Greeks name Ophioscoridon; in English Ramsies; growing of the owne accord in the fallow fieldes.”

Cornelius Agrippa (according to the English translation) has stated that the presence of the diamond also neutralizes the attractive power of the magnet. But as that great magician was somewhat inclined to quibbling, it is not impossible that by the word he uses for “diamond” (viz. adamas) he may mean the adamant or loadstone; which would reduce his assertion merely to this, that one magnet will counteract another.

Explore with AITake your curiosity a little further.
