The skull or "calavera" symbolizes many different things like equality between human beings, what remains on earth once we leave this world to another level, wisdom, and simplicity. I think the skeleton is a wonderful thing that our body creates itself as the oyster creates a pearl and its mother of pearl shell. It contains our history and holds our secrets of our path on earth. In Victorian times it's a memory of our loved ones already absent from this plane. What does the skull mean to you? - Monique
