The inverted torch is a true cemetery symbol, symbolizing life in the next realm or a life extinguished.

Inverted torches adorn the tombstone of Lewis Hutchison (February 29, 1792 - March 16, 1860) and his wife Eleanor Adams (April 5, 1800 - April 18, 1878) in Allegheny Cemetery near Pittsburgh, Pennsylvania.

A lit torch represents life, immortality and the everlasting life. Conversely, an inverted torch represents death, or the passing of the soul into the next life. Generally the inverted torch will still bear a flame, but even without the flame it still represents a life extinguished.
