With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick.
Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. These electrical lighting systems should also consider the impacts of, and ideally be integrated with, daylighting systems. Factors involved in lighting design are essentially the same as those discussed above in energy conservation analysis.
As these light sources change so does the practice of lighting Design. By the early 18th century, ornate cast ormolu forms with long, curved arms and many candles were in the homes of many in the growing merchant class. Neoclassical motifs became an increasingly common element, mostly in cast metals but also in carved and gilded wood. Chandeliers made in this style also drew heavily on the aesthetic of ancient Greece and Rome, incorporating clean lines, classical proportions and mythological creatures. Developments in glassmaking later allowed cheaper production of lead crystal, the light scattering properties of which quickly made it a popular addition to the form, leading to the crystal chandelier. During the 18th century glass chandeliers were produced by Bohemiens and Venetian glassmakers who were both masters in the art of making chandeliers.
