In it, he attributed the name "magnet" to the supposed discoverer of lodestone, the shepherd Magnes, "the nails of whose shoes and the tip of whose staff stuck fast in a magnetic field while he pastured his flocks". Pliny was killed during the volcanic eruption of Mount Vesuvius near Pompeii in A. 79 but his "Natural History" lived on as an authority on scientific matters up to the Middle Ages. C.) - one of the Seven Wise Men of Greece - was the first thinker to attempt to explain natural phenomena by means of some underlying scientific principle rather than by attributing them to the whim of the Gods - a major departure from previous wisdom and the foundation of scientific method, frowned upon by Aristotle but rediscovered during the Renaissance and the Scientific Revolution.He travelled to Egypt and the city state of Babylon in Mesopotamia (now modern day Iraq) and is said to have brought Babylonian mathematics back to Greece.Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.There are also claims that the Archimedes' Screw may have been invented in Mesopotamia and used for the water systems at the Hanging Gardens of Babylon. Fine metal working techniques were also developed in Egypt where filigree jewellery and cloisonné work found in Tutankhamun's tomb dating from 1327 B. was made from delicate wires which had been drawn through dies and then soldered in place. Fine wire also made by the Egyptians by beating gold sheet and cutting it into strips. Around this date, after his escape from Egypt, Moses ordered the construction of the Ark of the Covenant to house the tablets of stone on which were written the original "Ten Commandments".Egypt was also home to Imhotep the first man of science in recorded history. both of which refer to earlier works attributed to Imhotep. The process for making wrought iron was discovered by the Hittites, in Northern Mesopotamia and Southern Anatolia (now part of Eastern Turkey), who heated iron ore in a charcoal fire and hammered the results into wrought (worked) iron. Recorded in the Bible, Book of Exodus, Chapter 39, Verse 3, - "And they did beat the gold into thin plates, and cut it into wires, to work it. Its construction is described in great detail in the book of Exodus and according to the Bible and Jewish legend it was endowed with miraculous powers including emitting sparks and fire and striking dead Aaron's sons and others who touched it.

Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.

The technique was reputed to have been in use in China around the same time but no artifacts remain. In 1915 Nikola Tesla, in an essay entitled "The Fairy Tale of Electricity" promoting the appreciation of electrical developments, proposed what seemed a plausible explanation for some of the magical powers of the Ark.
