With the invention of fireside, the earliest type of synthetic lighting used to illuminate an space had been campfires or torches. As early as 400,000 BCE, fire was kindled within the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps had been created from naturally occurring supplies resembling rocks, shells, horns and stones, had been stuffed with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. A whole lot of these lamps (hole labored stones) have been discovered within the Lascaux caves in trendy-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
