In the Egyptian language, papyrus was called wadj (w3ḏ), tjufy (ṯwfy), or djet (ḏt).
The name Wadjet[5] is derived from the term for the symbol of her domain, Lower Egypt, the papyrus.[6]
Her name means "papyrus-colored one",[7] as wadj is the Ancient Egyptian word for the color green (in reference to the color of the papyrus plant) and the et is an indication of her gender. Its hieroglyphs differ from those of the Green Crown (Red Crown) of Lower Egypt only by the determinative, which in the case of the crown was a picture of the Green Crown[8] and, in the case of the goddess, a rearing cobra.
The Going Forth of Wadjet was celebrated on December 25 with chants and songs."
Osiris was considered not only a merciful judge of the dead in the afterlife, but also the underworld agency that granted all life, including sprouting vegetation and the fertile flooding of the Nile River. He was described as the "Lord of love",[11] "He Who is Permanently Benign and Youthful"[12] and the "Lord of Silence".[13] The Kings of Egypt were associated with Osiris in death – as Osiris rose from the dead so would they in union with him, and inherit eternal life through a process of imitative magic. By the New Kingdom all people, not just pharaohs, were believed to be associated with Osiris at death, if they incurred the costs of the assimilation rituals.[14]
Through the hope of new life after death, Osiris began to be associated with the cycles observed in nature, in particular vegetation and the annual flooding of the Nile, through his links with the heliacal rising of Orion and Sirius at the start of the new year.[12]
He was classically depicted as a green-skinned deity
