Historically,early forms of lighting around the world drew on whatever local materials wewe available. The first in the body of an oily fish - the oil would seep into the wick and give out a no doubt rather odiferous but still effective light. In South America, the native Indians caught huge glowing humming beetles and used them as s light source,while in japan, fireflies were trapped in wood and paper cages to provide an evening's worth of light.
