... "By His wisdom He crushed Rahab, by His breath the heavens are cleared, and His hand transfixed Nachash Bariach."  These words are often rendered "crooked serpent"; but it is more likely that they are to be regarded as proper names, taken from the old mythology.  Indeed they seem fairly easy to identify.  The term nahs (the equivalent of the Hebrew nachash) is applied to two planets, both supposed to bring ill luck, Saturn and Mars; and the latter of these is called in Arabic Mirrikh, which, by the alteration of the first letter to B (a change noticed above in the case of Bildad) becomes Bariach.  The word nahs is said to mean darkness, and especially that caused by particles of dust in the air...
