Hathor
In this image from Queen Nefertari's tomb, sky goddess Hathor wears her cow horns supporting the sun disk. This deity is sometimes seen leading a cow. Early versions of this goddess were associated with the Milky Way, which was perceived as an outpouring of milk from the heavenly cow.
The Great One of Many Names, Hathor, was worshipped from the early days of ancient Egypt. In the valley temple at Giza, she appears as the representative of Upper Egypt along with Bastet/Bast, who represents Lower Egypt.
Her epithets included Lady of Stars, Mistress of Heaven and Celestial Nurse. Her great importance merited both priests and priestesses. The image shows her preparing the queen for the underworld.
