What does nigredo mean?
Nigredo is Latin for blackness. It names the opening stage of the work, when the matter in the vessel is dissolved, burned or left to rot until it blackens. The texts picture it as a death: a raven, a skull, a king lying in a grave, the sun eclipsed.
The alchemists treated the black as a good sign, since nothing could be remade until it had first been taken apart. Carl Jung read the nigredo as the meeting with the shadow, the stretch of an inner change in which old certainties fail and the person sees what they had kept out of sight.

What sets Nigredo apart
The nigredo is the one stage every count of the work keeps, whatever else is dropped. Its operation is putrefaction, a slow rotting under gentle heat, and its metal and planet are lead and Saturn, which is why old texts speak of it in the language of melancholy. The alchemists' advice is the notable part: when the black appears, do not stop the fire. They read it as proof that the work had truly begun.
- Language: Latin: blackness; Greek melanosis
- Operation: putrefaction or mortification of the matter
- Metal and planet: lead and Saturn
- Images: the raven, the raven's head (caput corvi), the skull, the black sun
- Jung: the meeting with the shadow, compared with melancholy
Often mistaken for something else: Shadow work is a modern practice of looking at what one has disowned; the nigredo is the alchemical image Jung used for the stretch of life in which that looking is forced on a person.
The story behind Nigredo
Blackening, melanosis in Greek, is one of the colour stages already named in Greek alchemy of the first centuries. Latin authors called it nigredo and linked it with the operation of putrefaction and with Saturn and lead. Jung wrote about it at length in Psychology and Alchemy (1944) and Mysterium Coniunctionis (1955 to 1956), tying it to melancholy and to the confrontation with the shadow.
Why Nigredo matters
Nigredo is the stage the alchemists called necessary: the texts treat the black as proof the work has begun, not as failure.
How to read Nigredo
Readers use it to name a time of collapse or loss, and to ask what is being taken apart before anything new can be made.
Nigredo in practice: an example
After a job ends and the plans that hung on it fall away, a reader might name the flat months that follow their nigredo.
Where readings of Nigredo go wrong
Nigredo is an image, not a judgement of anyone's state of mind, and it never calls for staying in the dark on purpose.

Common questions
What does nigredo mean?
It means blackness. In alchemy it is the first stage, when the matter is broken down and turns black; as an image of inner change it is the dark opening stretch in which an old way of living comes apart.
What comes after the nigredo?
The albedo, the whitening, in which the blackened matter is washed. The full sequence is nigredo, albedo, citrinitas and rubedo, though many texts leave out the yellow stage.
Is nigredo the same as depression?
No. Nigredo is an image from alchemy that Jung compared with melancholy. It is not a medical term, and a low mood that lasts or deepens belongs with a doctor.
