Coal was known to man thousands of years ago. Ancient writings tell us that three thousand years ago the Chinese knew that certain kinds of black rock would burn, and in one part of the country where there was little wood they used to dig into the earth to find this black rock for their fires. This is the first evidence of coal being deliberately dug from the ground, but it is quite possible that even before this, coal was used for fuel in some parts of the world. Early man probably discovered it by accident, when he noticed that in some places the stones on which he built his fires would burn.
Outcrop coal was used in Britain during the Bronze Age (2-3000 years BCE), where it has been detected as forming part of the composition of funeral pyres.[1] It was also commonly used in the early period of the Roman occupation. Evidence of trade in coal (dated to about 200 CE) has been found at the inland port of Heronbridge, near Chester, and in the Fenlands of East Anglia, where coal from the Midlands was transported via the Car Dyke for use in drying grain.[2] Coal cinders have been found in the hearths of villas and military forts, particularly in Northumberland, dated to around 400 CE. In the west of England contemporary writers described the wonder of a permanent brazier of coal on the altar of Minerva at Aquae Sulis (modern day Bath) although in fact easily-accessible surface coal from what is now the Somerset coalfield was in common use in quite lowly dwellings locally.[3]
