I researched the significance of the Rainbow Goddess I found Hathor! I discovered that she, the Morning and Evening Venus Star Goddess, Mistress of Heaven, Celestial Nurse, Mother of Mothers, and Celestial Cow Goddess of the Milky Way was the original RAINBOW GODDESS.
First of all, Hathor was part of the triple Goddess of Heaven. Goddess Nun, who was the primordial waters, which gave birth to Mehet-Waret, the cow goddess of the sky. Her name actually means “great flood” or “tidal wave” and so she was the original destructive and regenerative force of Nun, which later transposed to Sehkmet. Hathor, was called the Morning and Evening star, because she represented the planet Venus or star Sirius which would rise after the flood. The Venus star at certain times of the year would rise in the morning and other times would rise at twilight. When the Venus star Sirius would rise, this was seen as the start, or re-birth, of the Sun and the solar yearly calendar. This may be why she was also seen as the Goddess of resurrection and was designed on many tombs and sarcophagi.
Hathor was known as the Goddess of a thousand names and one of Her names was Nut, the Sky Goddess. Nut was said to wear the rainbow and have stars across Her body. She like, Hathor and Mehet Waret were cow Goddesses, and they formed a great triple Goddess who reflected the supreme deity of Nun. In the Bible, and many other ancient texts, the Rainbow is seen as a covenant sign of God’s good will and love to not destroy them in a flood. Since, the name of the Goddess Mehet Waret, actually means “great flood” and she is the crone aspect of Nun, it would be surmised that Hathor is then the Mother aspect and the rising Rainbow, who is seven in color, as she is seven in faces and is a sign of joy, rebirth, love, happiness, beauty,music and dancing in celebration! The Seven Hathors would take of human form and were present at the birth of a child. They would then prophesy the child’s fate. They were called on for matters of love, protection from evil spirits and transformation. In Queen Nefertari’s tomb they were named: lady of the Universe, Sky-Storm, You from the Land of Silence, You from Khemmis, Red-Hair, Bright Red and Your Name Flourishes Through Skill.
