properties of the amber and the lodestone to a soul within
them. The name Electricity is derived from ELEKTRON, the Greek for
amber, and Magnetism from Magnes, the name of the shepherd, or, more
likely, from the city of Magnesia, in Lydia, where the stone occurred.
These properties of amber and lodestone appear to have been widely
known. The Persian name for amber is KAHRUBA, attractor of straws, and
that for lodestone AHANG-RUBA attractor of iron. In the old Persian
romance, THE LOVES OF MAJNOON AND LEILA, the lover sings--
'She was as amber, and I but as straw:
She touched me, and I shall ever cling to her.'
The Chinese philosopher, Kuopho, who flourished in the fourth century,
writes that, 'the attraction of a magnet for iron is like that of amber
for the smallest grain of mustard seed. It is like a breath of wind
which mysteriously penetrates through both, and communicates itself with
the speed of an arrow.' [Lodestone was probably known in China before
the Christian era.] Other electrical effects were also observed by the
ancients. Classical writers, as Homer, Caesar, and Plutarch, speak of
flames on the points of javelins and the tips of masts. They regarded
them as manifestations of the Deity, as did the soldiers of the Mahdi
lately in the Soudan. It is recorded of Servius Tullus, the sixth king
of Rome, that his hair emitted sparks on being combed; and that sparks
came from the body of Walimer, a Gothic chief, who lived in the year 415
A.D.
During the dark ages the mystical virtues of the lodestone drew more
attention than those of the more precious amber, and interesting
experiments were made with it. The Romans knew that it could attract
iron at some distance through an intervening fence of wood, brass, or
stone. One of their experiments was to float a needle on a piece of
cork, and make it follow a lodestone held in the hand. This arrangement
was perhaps copied from the compass of the Phoenician sailors, who
buoyed a lodestone and observed it set towards the north. There is
reason to believe that the magnet was employed by the priests of the
Oracle in answering questions. We are told that the Emperor Valerius,
while at Antioch in 370 A.D., was shown a floating needle which pointed
to the letters of the alphabet when guided by the directive force of
a lodestone. It was also believed that this effect might be produced
although a stone wall intervened, so that a person outside a house or
