This sheet shows the ceremony of the judgement of the dead before Osiris, the central god of Egyptian funereal rituals and ruler of the Underworld. Kerqun's heart, represented by the hieroglyph for 'heart', sits on the left pan of the scale to be weighed against a feather representing Maat. To the left of the scales waits the 'devourer', ready to consume the heart should it not balance with Maat. The judgement is proclaimed and recorded by the scribe Thoth, the ibis-headed god.
