I doubt whether Hathor’s ‘hairdo’ was initially inspired by comets attributes alone, although there is undoubtedly a connection (material curling around an astral body) Hathor’s other many attributes and epithets just do not correspond. Whereas my identification allows us to take so many of Hathors attributes at face value.
A few more examples;
In her funerary aspect, she was known as ‘lady of the west.’ Each evening she was considered to receive the setting sun (Red sun), which she then protected until the morning. This is the sun many times appearing amidst Earth’s thick band (as in wide) of debris as it set in the west.
‘She was the goddess most associated with the dessert and foreign countries.’
East and west of the Nile Valley we have deserts, Hathor (earths ring) from an Egyptian perspective would stretch from the eastern deserts arch across the sky and ‘set’ over the western desert.
The dying desired to be ‘in the following of Hathor’ so they would enjoy similar protection in the netherworld.
In we take my scenario (GKS) of a sky crowded with bodies (Mars, Venus, asteroids and comets) and these were believed to be ‘doubles’ (Egyptian kas, Egyptian dualism) of people here on earth - celestial kas that the Egyptian’s believed they joined with after death, then we can see why Hathor as Earth’s ring was perceived as leading the deceased to a life of eternity in the west. Earth would probably spin faster than its ring (s), so Hathor and her 'inhabitants,' from ground level would move from east to west, essentially following the sun – hence ‘in the following of Hathor.’ This also leading to the belief that some 'bodies' would spend a life eternal with the sun god Re.
Hathor was also considered the daughter of Re, given their celestial association we can see why.
Something else against the primary comet association would be Hathor’s longevity, she is attested to from the earliest of times, a perennial universal deity spanning some three millennia. Comets, on the other hand, although possibly remaining in the skies for several months, are too periodic.
Hathor – the sky cow interacting ‘suckling’ with the kas or doubles of the people here on Earth. An analogous situation with Saturn's moon Prometheus ‘sucking out’ some of the dust particles from Saturn’s F ring.
Hathor Suckling Tuthmosis or as I Interpretate, the moon as Tuthmosis ("born of the god Thoth," literally) sucking material from earth's ring.
I’ve added some of the books you mentioned to my ‘inbox.’
