Originally, a torch was a portable source of fire used as a source of light, usually a rod-shaped piece of wood with a rag soaked in pitch and/or some other flammable material wrapped around one end. Torches were often supported in sconces by brackets high up on walls, to throw light over corridors in stone structures such as castles or crypts. Tiki torches are a popular decorative element.
