Tropical nature has equipped humanity with everything it needs: food, clothing, and light.
On the islands of the Pacific Ocean and in certain regions of South America, there are plants whose fruits the locals refer to as “candle nuts.” These fruits are edible, but they also serve a practical purpose for lighting homes. When lit, a candle nut burns for a long time with a steady flame, producing no smoke or soot.
However, the harsh North has not left people without their own natural “candles.” Here, instead of nuts, they used marine animals—lampreys, which closely resemble fish. These were caught, dried, and wicks were threaded through their mouths before being lit. These sea-caught “candles” were used in the North until electricity arrived.
