Electricity -- Biography
During that long period nothing of importance was added to the magnetic
lore of the world. True, a few fables were dug out of the tomes of
ancient writers which gained credence and popularity, partly by reason
of the fondness of the human mind for the marvelous, and partly also by
reason of the reputation of the authors who stood sponsors for them.
Pliny (23-79 A. D.) devotes several pages of his "Natural History" to
the nature and geographical distribution of various kinds of lodestones,
one of which was said to repel iron just as the normal lodestone
attracts it. Needless to say that the mineral kingdom does not hold such
a stone, although Pliny calls it _theamedes_ and says that it was found
in Ethiopia.
Pliny is responsible for another myth which found favor with subsequent
writers for a long time, when he says that a certain architect intended
to place a mass of magnetite in the vault of an Alexandrian temple for
the purpose of holding an iron statue of Queen Arsinoe suspended in
mid-air. Of like fabulous character is the oft-repeated story about
Mahomet, that an iron sarcophagus containing his remains was suspended
by means of the lodestone between the roof of the temple at Mecca and
the ground.
As a matter of fact, Mahomet died at Medina and was buried there in the
ordinary manner, so that the story as currently told of the suspension
of his coffin in the "Holy City" of Mecca, contains a twofold error, one
of place and the other of position. By a recent (1908) imperial irade of
the Sultan of Turkey, the tomb is lit up by electric light in a manner
that is considered worthy of the "Prophet of Islam."
Four centuries after Pliny, Claudian, the last of the Latin poets as he
is styled, wrote an idyl of fifty-seven lines on the magnet, which
contains nothing but poetic generalities. St. Ambrose (340-397) and
Palladius (368-430), writing on the Brahmans of India, tell how certain
magnetic mountains were said to draw iron nails from passing ships and
how wooden pegs were substituted for nails in vessels going to
Taprobane, the modern Ceylon. St. Augustine (354-430) records in his "De
Civitate Dei" the wonder which he felt in seeing scraps of iron
contained in a silver dish follow every movement of a lodestone held
underneath.
