Nephthys (Nebt-Het)-Sister of Osiris and Isis; Wife of Set; Mother of Anubis. Born on the 5th and last day of the epagomenal days. Sometimes seen as a Netert /Goddess of incredible sadness. She envied her sister Isis and her happy marriage so much that she attempted to look just like her. One night Nephthys sat weeping outside the home of Osiris and Isis. Osiris came upon her and mistook her for his wife, Isis. Anubis was born as a result.

Nephthys is a goddess of undetermined origin, but contrary to many erroneous claims, her Egyptian name did not, in any way, mean "Lady of the House" as a human home. Rather, her name means, quite specifically, "Lady of the Temple Enclosure," which likely indicates the association of this goddess with one particular temple or some specific aspect of the Egyptian temple that is now partially lost to modern understanding. We do know, at least that (along with her sister Isis) Nephthys represented the temple pylon or the great flagstaff heralding the Divine Dwelling.

Nephthys, the Hidden One, sometimes seen as the alter ego or dark side of Isis; ruler of the deep waters of the unconscious, the dark side of the moon. She is essentially a water netert, the feminine aspect of Neptune, and as such, she rules the emotions and relates strongly to the human condition.

By the time of the Fifth Dynasty Pyramid Texts, Nephthys appears as a goddess of the Heliopolis cosmic family, the female companion of the war-like deity Set. She is likewise the counterpart of her sister Isis in her capacity as a protective goddess who symbolized the transitional death experience, just as Isis represented the transitional birth experience. In the funerary role, Nephthys was often depicted as a kite, a milan falcon, or as a woman with a falcon's wings, usually outstretched as a symbol of protection. She was almost without fail depicted as crowned by the hieroglyphics signifying her name, which were a combination of signs for the sacred temple enclosure (hwt), along with the sign for neb,or "mistress (Lady)," atop the enclosure.

Because Set represented the barren desert, he was generally viewed as a sterile deity. Therefore, Nepthys was, in some districts, seen as a childless entity as well. Her early association with the kite or the Egyptian hawk (and its piercing, mournful cries), reminded the ancients of the lamentations offered for the dead by wailing women, and thus Nephthys was associated with death and putrefaction from the earliest known epoch.

Indeed, in the Pyramid Texts her hair is compared to the strips of linen that enshroud the deceased Pharaoh, who is encouraged to "break free" from the tresses of Nephthys and ascend to the afterlife. In this sense, Nephthys was viewed as an ominous but crucial impediment; the Pharaoh becomes strong for his journey to the afterlife by breaking free from Nephthys. The same could be applied later to all of the dead, who considered Nephthys as a necessary companion. According to the Pyramid Texts, Nephthys, along with Isis, was a force before whom demons trembled in fear, and whose magical spells were necessary for navigating the various levels of Duat, or the afterlife. In a similar vein, Nephthys was not viewed as the polar opposite of Isis, but rather as a different reflection of the same reality: eternal life in transition. Thus, Nephthys was seen as occupying the night-bark on the journey of Ra, the sun god, particularly when he entered Duatat the transitional time of dusk, or twilight. Isis was his companion at the coming of dawn.

Nephthys plays an important role in the Osirian myth-cycle, for it is her magical power in conjunction with that of Isis that not only reconstitutes and resurrects the body of Osiris, but serves to fiercely protect and nurture the child Horus. In Egyptian temples, the magical powers that kept chaos at bay were intrinsically linked to the protection of the Osirian "mummy" residing in each temple. As part of the crucial protective dyad, Nephthys was essential to the maintenance of ma'at, or balance for the good of temple, town, kingdom, and royal household. Though Nephthys was normally depicted in myth as being estranged from Set and loyal to Osiris and Isis, she was nevertheless worshipped as Set's companion and, in many localities, she shared both his fearsome and his ribald attributes.

Again, Nephthys was a goddess with far more flexibility than many researches have previously bothered to note. As a mortuary goddess, she was one of the four protectresses of the sacred Canopic jars and of the genii Hapi, in particular. Hapii guarded the embalmed lungs, and as Mistress, Nephthys was a goddess capable of delivering the "breath of life" to the deceased via her wings. In the city of Memphis, Nephthys was honored with the title "Queen of the Embalmer's Shop," and elsewhere associated with the dog-headed god Anubis, who in some myths is considered to be her offspring via an illicit relationship with Osiris, when sister Isis wasn't watching. Other myth-cycles and inscriptions, however, describe Anubis as the offspring of the goddess Hesat, or of a union between Nephthys and Ra.

Nephthys' greatest role was clearly as the stalwart companion of Isis. Because of the power shared between the two sisters, the ancient Egyptians naturally had great recourse to Nephthys. She was quite often described in temple texts as a youthful, nubile, and beautiful young goddess, which would facilitate her later identification with Hathor. At the same time, Nephthys was a particularly festive deity whose temple rites and feasts included the liberal consumption of beer. In various texts, Nephthys is shown offering the Pharaoh beer "to make him happy" and using her magic to prevent any possibilty of "hangover." Elsewhere, Nephthys is a goddess who gives the Pharaoh power to see "that which is hidden by moonlight." This fits well with textual themes that consider Nephthys to be a goddess whose unique domain was darkness, or the edge of the desert.
