With the discovery of fire, the earliest form of artificial lighting used to light up an area had been campfires or torches. As early as four hundred,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric folks used primitive oil lamps to light up surroundings. These lamps had been created from naturally occurring supplies corresponding to rocks, shells, horns and stones, had been full of grease, and had a fiber wick. Lamps typically used animal or vegetable fat as fuel. A whole lot of these lamps (hollow labored stones) have been discovered in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) had been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps had been also invented
