In late-17th-century Paris, the first public lanterns appeared as part of oil lamps used to light city streets. Oil lamps with reflectors were soon developed. The first public oil lamps in Milan were financed by revenues from a lottery. These were lanterns containing an oil lamp with a number of wicks. The shades over these lit wicks spread the light over a distance, making the lamp more effective. Diffusing light also made light beams more palatable to the eyes. Lampshades have been in use ever since. Oil lamps are pretty rare in the 21st century, but lampshades of all types are pretty common. Watch as this master woodworker turns a discarded piece of firewood into an impressive lampshade.
