It may well be that all these puns on the determinative hieroglyphic sign for Sirius came, in the usual way with the pun-loving Egyptian priests, to form a complicated body of Sirius doctrine involving teeth, Earth-borne, ring-shaped, falcon or hawk (Circe), etc., etc. It should therefore not surprise us in the least to learn that the ancient Egyptian word for ‘tooth’, abeh, has exactly the same hieroglyphic as the word for Earth. Hence the origin, almost without question, of the connection between teeth and the Earth: in ancient Egypt they were written by the identical sign, which were tilted forms of the same sign used to represent Sirius! (p. 236, 1998 ed.)
But all of this has precedent in “alternative” scholars dating back pretty much as far back as we can look. The “Ark-ist” theorist Jacob Bryant proposed that Egypt was descended from Noah’s son Ham because they worshiped the god Amon, whom he chose to see as (H)am-on, the deified Ham, who in turn was also the sun god and thus the sun god of most European mythologies.
Before this, the ancient Greek rationalist writers tried to seek out the “truth” behind ancient myths by looking into the words used in them and proposing fanciful explanations based on look-alike or sound-alike words. Euhemerus was the most famous of these scholars, though Dionysus Schytobrachion offered some of the most entertaining "explanations."
As reported in Diodorus Siculus, Dionysus thought the story of the fire-breathing bulls (tauroi) of Colchis resulted from etymological confusion of bulls with the land of Taurica:
[Aeëtes] built a wall likewise round the temple, and placed a strung guard of Taurican soldiers to keep it, which has afforded matter for prodigious stories among the Grecians; as how that bulls which breathed out fire at their nostrils guarded the temple, and that a dragon kept the fleece. For by reason of the ambiguity of the word Taurus, it was strained to signify the fierceness and violence of bulls; and the cruel murdering of strangers, gave rise to the fiction of the bulls breathing out fire.
