This is said to have been the name of the last Knights Templar ship that escaped from Acre in 1291.  It is said to have carried on it a great secret that the Vatican wished to keep quiet.  The secret is said to have included the secret writing of Jesus in which he is said to have claimed to be just a man and not the Son of God.  If this is true and ever becomes common knowledge it would probably destroy the Christian Religion.
