The serai or the traditional lantern is one of the methods by which homes and places of residence, such as areesh, were illuminated. It is a vessel in which (kerosene) is placed and a crystal bulb or transparent bottle (farsha) is affixed to the vessel. It is supplied with a wick to absorb the kerosene from the vessel, which is then wrapped with a date so that it remains connected to the top of the bottle. When the wick is lit, the light spreads throughout the bottle, and continues to do so as the wick absorbs the kerosene stored in the vessel.
