A lamp is a device for providing illumination, originally a jar containing a wick-soaked inflammable substance, and later other light-generating technologies such as gas and electric lamps.

Since at least 70,000 BCE, light has been present. It was created by hollowing out a rock and filling it with moss or other absorbent material, which was then soaked in animal fat and lighted. In the Mediterranean and the Middle East, the earliest light was fashioned like a shell. Real shells were used at first, with sections chopped off to create room for the lighting area; later, they were replaced with earthenware, alabaster, or metal lamps that were meant to seem like their natural counterparts. In ancient Egypt and China, the saucer lamp was a crucial type of early illumination. A spike in the center of the declivity was occasionally employed to support the wick, which was utilized to control the rate of burning. It might have been fashioned out of pottery or metal. Another variation added a wick channel, which allowed the wick’s burning surface to dangle over the edge. The latter gained popularity in Africa before spreading to East Asia.

Lamps did not appear in ancient Greece until the 7th century BCE when torches and braziers were replaced. The word lamp is derived from the Greek word lampas, which meaning torch. A Greek lamp was made of earthenware and resembled a shallow cup with one or more spouts or nozzles where the wick burned, as well as a circular hole in the top for filling and a carrying handle. Such lights were commonly coated in a heat-resistant red or black finish. A more expensive variant was made using bronze. A ring for the finger and a crescent above it for the thumb was the standard pattern. Bronze hanging lights were very popular.

The Romans came up with a novel way of making terra-cotta lamps that included using two molds and then joining the parts. Metal shapes became more complicated, often taking on animal or vegetable forms; in the first century CE, particularly large versions for use in circuses and other public spaces appeared.

There is scant evidence of medieval lights, but those that did exist appear to be open, saucer-style lamps that functioned poorly when compared to the closed lamps used by the Romans. In Europe in the 18th century, the advent of a central burner, which came from a closed container through a metal tube and was regulated by a ratchet, was a key step forward in the evolution of the lamp. The discovery that aeration and a glass chimney may improve the flame created coincided with this achievement. Until the late 18th century, the main fuels used in lamps were vegetable oils such as olive oil and tallow, beeswax, fish oil, and whale oil. When the first well for petroleum oil was dug in 1859, the kerosene lamp (paraffin in British use) became popular. Meanwhile, coal gas, and later natural gas, were becoming increasingly popular as lighting sources.
