What is the symbol of the Sicilian Mafia?

The Sicilian Mafia does not maintain a tangible symbol. Operating in secret, the Sicilian Mafia strives to leave as little physical evidence of their existence as possible.

Although lacking a tangible symbol, a phrase used by the Sicilian Mafia perhaps best symbolizes the perception of its members of themselves and the manner in which they self-identify. That phrase is "Costa Nostra," which translate into English as "our thing." The Telegraph in London reports that initiates must spill their own blood on the image of a saint, which is then set on fire. Although not a specific symbol of the Costa Nostra in its entirety, the act described by the paper is rich with symbolism.
