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.
A torch carried in relay by cross-country runners is used to light the Olympic flame which burns without interruption until the following Olympics. These torches and relay tradition were introduced in 1936 Summer Olympics by Carl Diem, chairman of the event because during the duration of the Ancient Olympic Games in Olympia, a sacred flame burns inside of the temple of Hera, kept in custody by her priestess.
Juggling torches are often used as a prop in toss juggling: they can be flipped into the air in an end-over-end motion while being juggled, in the same manner as juggling clubs or juggling knives, but because of their sound and 'trail of flame', they can appear much more impressive to audiences. To a skilled juggler, there is only a slight chance of being burned, but they are still dangerous.
The torch is a common emblem of both enlightenment and hope. Thus the Statue of Liberty, actually "Liberty Enlightening the World", lifts her torch. Crossed reversed torches were signs of mourning that appear on Greek and Roman funerary monuments--a torch pointed downwards symbolizes death, while a torch held up symbolizes life, truth and the regenerative power of flame. The torch is also a symbol used by political parties such as the British Conservative Party and the Malta Labour Party.
In former times, liturgical torches were carried in Eucharistic processions simply to give light. The Church eventually adopted their use for Solemn High Masses.
According to Adrian Fortescue ("The Mass: A Study of the Roman Liturgy "), the more correct form of liturgical torches are non-freestanding (i.e. cannot stand up on their own). However, today, even in the Vatican, freestanding, tall candles in ornate candle-stick holders have replaced the former type. The torches are carried by torchbearers, who enter at the Sanctus and leave after Communion.
