The ravens head of alchemy which is also called the black stage signifies the alchemical “death” of the matter being worked upon by the alchemist as the substance is washed clean of its original sin. This sign marks the consummation of the royal wedding of the sun and moon in which a good union has taken place. Decomposition or putrefaction is the sign the alchemist must see before the philosophical or alchemical regeneration of matter can occur which then signifies the rebirth of the supernatural son of the sun. The phoenix risen from the ashes of the black alchemical sun.
