Lighting

Almost 500 000 years, as people learned to use fire for illumination. Over the centuries, all the lamps were improved, and today, clicking a switch, you can strike with light the whole streets and houses.
When the first man dipped a wick in animal fat filled the crock to turn it into a lamp, it is difficult to say, but the ancient primitive lamp with chalk or Sandstone scholars date to approximately 40,000 BC, and in Iraq were found ceramic fixtures that existed about 10,000 years.
As evidenced by the Bible, made from the same animal fat candles flickered in the temple of Solomon in the X century BC, Since without them, there hasn't been a single service, however, the widest application in the home of a man they found only in the middle ages.
