Circulatio represents the cyclical or iterative nature of alchemical processes, symbolizing the continuous circulation and transformation of energies.
The Pelican
In alchemical symbolism, the motif of the pelican puncturing its breast to feed its young with its blood represents self-sacrifice, nurturing, and redemption, often drawing from Christian imagery of Christ's sacrifice. It embodies the alchemical process of transformation where the substance "feeds" itself through circulation and distillation, akin to the pelican vessel apparatus that recirculates vapors to purify and exalt the matter. Spiritually, it signifies the alchemist's inner regeneration, drawing from personal essence to achieve higher states, and the dissolution of the philosopher's stone in a medium to multiply its power.
This motif typically occurs during the rubedo (reddening) stage of the alchemical process, the final major phase after nigredo (blackening) and albedo (whitening), where the matter achieves its perfected red form as the philosopher's stone or red elixir. In sequences of alchemical birds, it follows the white swan (albedo) and peacock (iridescent transition) but precedes the phoenix (ultimate completion), marking the point of coagulation, multiplication, or projection where the stone nourishes and transmutes base elements.
