Nephthys, was the daughter of Seb and Nut, and the sister of
Osiris, and Isis, and Set, and the wife of Set, and the mother of
Anpu, or
Anubis, either by Osiris or Set. The name "Nebt-het" means the "lady of the house," but by the word "house" we must understand that portion of the sky which was supposed to form the abode of the Sun-god
Horus; in fact "het" in the name of Nebt-het is used in exactly the same sense as "het" in the name "Het-Hert," or
Hathor, i.e., the "house of Horus." In the earliest times Nephthys was regarded as the female counterpart of Set, and she was always associated with him; nevertheless she always appears as the faithful sister and friend of Isis, and helps the
widowed goddess to collect the scattered limbs of Osiris and to
reconstitute his body. In the Pyramid Texts she appears as a friend of the deceased, and she maintains that character throughout every Recension of the Book of the Dead; indeed, she seems to perform for him what as a nature goddess she did
for the gods in primeval times when she fashioned the "body" of the "Company of the Gods," and when she obtained the name Nebkhat, i.e., "Lady of the body {of the Gods}."
The goddess is represented in the form of a woman who wears upon her head a pair of horns and a
disk which is surmounted by the symbol of her name, or the, " symbol only; and her commonest titles are, "
dweller within
Senu," "lady of heaven," "mistress of the gods," "great goddess, lady of life," "sister of the god, eye of Ra, lady of heaven, mistress of the gods," "lady of heaven, mistress of the two lands," "sister of the god, the creative goddess who liveth within An," etc. The chief centres of her worship were Senu, Hebet, (Behbit), Per-mert, Re-nefert, Het-sekhem, Het-Khas, Ta-kehset, and Diospolites. In the vignettes of the Theban Recension of the book of the Dead we find Nephthys playing a prominent part in connection with
isis, whose efforts it seems to be her duty to second and to forward. She stands in
the shrine behind
Osiris when the hearts of the dead are
weighed in the Great Scales in the presence of the god; she is seen kneeling on, by the side of the
Tet, from which the disk of the Sun is thrust upwards by the "living Ra," at sunrise; she is one of the "great sovereign chiefs in Tettu," with Osiris,
Isis, and Heru-netch-hra-f; and she kneels at the head of the
bier of Osiris and assists him to arise.
