What is the weighing of the heart?
The weighing of the heart is the decisive moment of the Egyptian journey after death. In the Hall of Two Truths the dead person stands before Osiris and forty-two assessors and declares, one by one, the wrongs they have not done. The heart, which the Egyptians regarded as the seat of thought and memory, is placed in one pan of a scale and the feather of Ma'at in the other. Anubis checks the balance, Thoth writes down the result, and the monster Ammit waits beside it.
If the heart balances, the person is declared true of voice and led to Osiris. If it is heavy with wrongdoing, Ammit eats it and the person ceases to exist. The papyri always show the favourable outcome, since each was made to secure it for its owner.

What sets Weighing of the Heart apart
The Egyptian judgement uses an instrument. No god simply pronounces: a balance is read, and the reading is written down by a scribe, as in an Egyptian court or counting house. The standard is equally exact, a single feather, so the heart must be no heavier than truth itself. Failure means annihilation and not torment, which separates this trial from later pictures of hell. The speech of denial that goes with it lists concrete wrongs such as theft, false measure and cruelty.
- Text: Book of the Dead, spell 125
- Place: the Hall of Two Truths, before Osiris
- Attendants: Anubis at the scale, Thoth recording, Ammit waiting
- Assessors: forty-two, each addressed in the declaration of innocence
- Verdict sought: maa kheru, true of voice
- Related spell: 30B, on the heart scarab, asking the heart not to bear witness
Often mistaken for something else: Ma'at is the principle and goddess of truth and order; the weighing is the single scene in which a life is measured against her feather.
The story behind Weighing of the Heart
The scene belongs to spell 125 of the Book of the Dead and is common from the New Kingdom, after about 1550 BCE; the idea of a judgement is older and appears in the Coffin Texts. Spell 30B, often inscribed on a stone scarab laid over the heart, asks the heart not to testify against its owner. The best known paintings are in the papyri of Ani and of Hunefer, both in the British Museum.
Why Weighing of the Heart matters
Weighing of the Heart is one of the earliest pictures of a moral judgement after death, in which conduct and not rank is what is measured.
How to read Weighing of the Heart
Readers return to it as an image for an honest account of a life, asking what would weigh on the heart if it were set on the scale today.
Weighing of the Heart in practice: an example
A museum visitor before the Papyrus of Hunefer can read the scene left to right: Anubis leading the man in, the scale, Thoth recording, and Horus presenting him to Osiris.
Where readings of Weighing of the Heart go wrong
Weighing of the Heart is religious teaching about what cannot be checked, and the spells show Egyptians also sought ritual protection in the trial.

Common questions
What is the weighing of the heart?
It is the Egyptian judgement scene in which the heart of a dead person is weighed against the feather of Ma'at to decide whether they may enter the blessed afterlife.
What happens if the heart is heavier than the feather?
The heart is devoured by Ammit, a creature part crocodile, part lion and part hippopotamus, and the person suffers the second death: they simply cease to be.
Why was the heart weighed and not the brain?
The Egyptians held the heart to be the centre of thought, feeling and memory, the organ that knew what a person had done. It was left in the body at mummification for that reason.
