Real, but the surviving record is thin or comes from one period only. In the record from the very beginning.
Nephthys nbt-ḥwt
lady of the house, the other mourner
The figure, plainly
The one who is always in the picture
A retelling, not a translation. What follows is the story as it is commonly told, drawn together from the better popular and scholarly accounts. It is not keyed to any single ancient text, and the ancient sources rarely agree with each other as neatly as a retelling has to. The attested record — with its sources, its gaps, and its disagreements — is below.
Nephthys is in almost every important scene in Egyptian religion and is the subject of almost none of them.
She is Isis's sister. She is Set's wife. She is at the head of the bier while Isis is at the foot. In the later story she is Anubis's mother. She is present, constantly, for three thousand years — and if you go looking for her story, the one where she is the person things happen to, it is not there.
That is not a gap in the record. That is what she is.
The other mourner
The image you have seen, even if you did not know what you were looking at: two women kneeling at either end of a body, arms out, wings sometimes, heads bowed.
Isis at the feet. Nephthys at the head. Every time.
They are the professional mourners of Egyptian religion, and the pairing is so fixed that it stops being about Osiris at all — it gets applied to ordinary dead people, on coffin after coffin, for centuries. Two goddesses turn up for a scribe from Thebes exactly as they turned up for a murdered king.
There were ritual texts for this, performed by two priestesses speaking their parts. Which means somewhere in Egypt, on a regular basis, two women stood at either end of a body and said the lines, and one of them was Nephthys.
Married to the murderer
Here is the thing nobody in the tradition seems bothered by.
Nephthys is Set's wife. Set kills Osiris. Nephthys spends the rest of the story helping Isis recover the body, mourn him, and raise the child who will avenge him.
Nobody treats this as a conflict. There is no scene where she chooses, no accusation, no moment of divided loyalty. She is married to one brother and on the side of the other, permanently, and the texts simply proceed.
Which tells you something about how Egyptian divine marriage worked — it is a position in a structure, not a statement about whose team you are on. She occupies a slot. The slot happens to be next to Set.
In the late version of the story she has a child by Osiris — Anubis — and Isis raises him. Note that this comes to us from Plutarch, writing in Greek around 100 CE, and should be attributed to him rather than assumed to be ancient Egyptian doctrine.
Lady of the house
Her name is written with two signs stacked on her head: a basket over a building. Nebet-hut — lady of the house, or mistress of the mansion.
Which house is not settled. A temple enclosure, possibly. The sky, possibly. Somebody's actual household, possibly. It is one of those Egyptian names that looks perfectly clear until you try to say what it means.
Those two signs are also the only way to tell her apart from Isis in a lot of scenes. Same posture, same wings, same kneeling. Read the headgear or you will get it wrong — and if there is no headgear, read the position: head of the bier is Nephthys.
No temple worth the name
She has essentially no independent cult. No Karnak, no Dendera, no great pilgrimage site. She appears in funerary equipment — coffins, canopic chests, shrine walls — which is to say she appears wherever there is a dead person to attend to, and nowhere there is a crowd to impress.
Modern esoteric and revival traditions have given her a great deal more prominence than she ever had, usually as a goddess of hidden or threshold things. That is a genuine modern development and worth knowing about as such — but it is not a recovery of something the Egyptians thought. It is a new reading of a goddess who was, in her own time, defined almost entirely by who she stood next to.
There is something quietly affecting about that. Somebody has to be at the head of the bier.
Overview
Nephthys is defined almost entirely by proximity. She is Isis's sister and constant companion, Set's wife, and — in the tradition that develops later — Anubis's mother by Osiris. She appears at the head of the bier when Isis is at the foot. She is rarely the subject of a story; she is present in other people's.
Her name, nbt-ḥwt, means "lady of the house" or "mistress of the mansion," and it is written as exactly that: a basket sign over a house sign, worn on her head. Whether "house" here means a temple enclosure, the sky, or a household is not settled.
This entry is partial rather than full because the record genuinely is lopsided: Nephthys is everywhere in funerary contexts and almost absent from narrative and cult. That shape is itself the finding, and padding it out with material borrowed from Isis would misrepresent it.
Attestation history
Old Kingdom. Nephthys is present in the Pyramid Texts, paired with Isis as a protector of the dead king [sethe-1908]. The pairing is there from the start.
Middle and New Kingdom. The two sisters as mourners become a standard funerary composition, applied to ordinary burials. Nephthys is one of the four goddesses who guard the canopic chest, with Isis, Neith, and Serqet — she is paired with Hapy, guardian of the lungs.
Late tradition. Plutarch gives the account in which Nephthys, married to Set, conceives Anubis by Osiris, and Isis raises the child [plutarch-iside]. This is a Greek-language source of c. 100 CE and should be attributed to it rather than assumed to be ancient Egyptian doctrine.
What the texts say
The lamentations. Ritual texts give Isis and Nephthys spoken parts as mourners, performed by two priestesses. These Lamentations of Isis and Nephthys are among the few Egyptian religious texts with an explicit performance instruction attached — they specify who speaks, and how.
The search. Nephthys accompanies Isis in the search for Osiris's body. She is a participant throughout the central myth without ever being its agent.
Married to the adversary. She is Set's consort, and consistently on Osiris's side. The tradition never treats this as a conflict requiring resolution, which is worth noticing: divine marriage here does not imply alignment.
Iconography
A woman wearing the basket-over-house hieroglyphs that spell her name. She is otherwise depicted almost identically to Isis — same posture, often winged with arms outstretched — and in funerary scenes the two are distinguished only by the headdress, and by position: Nephthys at the head of the bier, Isis at the foot.
Cult and practice
Nephthys has no great temple of her own. She is worshipped in association with other deities and appears in funerary equipment across all periods — coffins, canopic chests, shrine walls. Her presence is in the burial, not the temple estate.
Reception
Modern esoteric and revival traditions have given Nephthys considerably more prominence than the ancient record does, typically as a goddess of hidden things or of the threshold. That is a modern development, dated and documented as such — not an ancient reading recovered.
