These lamps were constructed from naturally occurring supplies similar to rocks, shells, horns and stones, were full of grease, and had a fiber wick. Lamps typically used animal or vegetable fat as fuel. Hundreds of these lamps (hollow worked stones) have been discovered within the Lascaux caves in trendy-day France, relationship to about 15,000 years ago.
