Much of the text to be covered here, continued from the end of 1.3.5 to the end of 1.4.6, is a lengthy digression about the ancient Gauls, and, at the beginning of that digression, we find a passing reference to a myth that has intrigued me for four and a half decades. In my comments, I concentrate on that myth, which is about a cosmic crash that happened once upon a time when Hēlios, god of the sun, made the mistake of allowing his solar chariot to be driven across the sky, just for one day, by a chariot driver other than himself. That other driver turned out to be the most reckless of all chariot drivers in ancient Greek myth. He was the mortal son of Hēlios, the hero Phaethon.
