The earliest hominids' use of fire may have been for guarding against animal predators, which may be the sum of their legacy to Homo sapiens sapiens. By the time that writing first appeared this use of fire had been considerably extended. What then did all this involve? THE MASTERY OF FIRE 9 Fire is essentially an epiphenomenon which takes many different forms: in everyday life these extend from the flash of an explosion to the smouldering of tobacco. The fire characteristic of the stars can be seen in the sun, still our main source of heat and light, but the process of combustion within the sun only began to be understood in the twentieth century.
The furnace can be designed with a conduit allowing the liquid mass to flow to the outside; an alternative is to have the process take place in a crucible, from which the liquid mass can be poured. In either case, the resulting product little resembles the ore from which it was extracted: it has become quite recognisably something new - a metal. Metal, in modern science, is above all a good conductor of electricity. Until Volta invented his electrochemical battery in 1800, there was no means of producing an electric current to be conducted anywhere, so we must look elsewhere for the important properties of metal in the ancient world.
As the Roman Empire came to its end, such a domain did develop in the West, with its basic unit, the pound (libra), being the standard both for money and for weight. 44 The monetary system that then resulted became standard in Western Europe under Charlemagne at the beginning of the ninth century: it survived in the United Kingdom until 1971. Confusion in metrology was a major obstacle to the development of science, and standardisation was long in coming.
