The use of candles dates back as far as 3,000 B.C., when ancient Egyptians used papyrus reeds dipped in animal fat that they then lit to use as torches. Similarly, ancient Romans dipped wicks into tallow, a rendered form of animal fat, to create another early form of the candle. Other components of candles include plants, insects, seeds and nuts which have been identified in Chinese, Japanese and Indian civilizations.
