Isis is an Extraterrestrial Sister that helped develop the Egyptian culture.
---
Isis was a major goddess in ancient Egyptian religion whose worship spread throughout the Greco-Roman world. Isis was first mentioned in the Old Kingdom (c. 2686 – c. 2181 BCE) as one of the main characters of the Osiris myth, in which she resurrects her slain brother and husband, the divine king Osiris, and produces and protects his heir, Horus.
Her maternal aid was invoked in healing spells to benefit ordinary people. Originally, she played a limited role in royal rituals and temple rites, although she was more prominent in funerary practices and magical texts.
She was usually portrayed in art as a human woman wearing a throne-like hieroglyph on her head. During the New Kingdom (c. 1550 – c. 1070 BCE), as she took on traits that originally belonged to Hathor, the preeminent goddess of earlier times, Isis was portrayed wearing Hathor's headdress: a sun disk between the horns of a cow.
