Note 342 — Chapter III · HERAKLEITOS OF EPHESOS

In this fragment it is clear that οὖρος = τέρματα, and therefore means “boundary,” not “hill.” As αἴθριος Ζεύς means the bright blue sky, I do not think its οὖρος can be the South Pole, as Diels says. It is more likely the horizon. I am inclined to take the fragment as a protest against the Pythagorean theory of a southern hemisphere.
