Typically the first to be used for light was the fire or campfire. After that candles or wax. After the candles, a Kerosene lamp was usually used. Some cities or villages used gas lighting before electricity was established. By gas I mean natural gas or propane burning inside a "mantle" in a lamp specifically made for this.
