Crow
A crow is a messenger between heaven and Earth, an omen of death, and prophet of the hidden truth or the unconscious. Because of its black color, the crow is often associated with evil.
Like the raven, the crow in alchemy represents the nigredo, the initial blackening and putrefaction that initiate the process of the Great Work.
