So that's one language (which elsewhere was (+,*,S,<,0) from Shoenfield
page 22, I think). Why do you need another?

Prove that odd(x) can't be expressed positively in L(0,<,*), begin by
defining "expressed positively".

Sorrow in all lands, and grievous omens.
Great anger in the dragon of the hills,
And silent now the earth's green oracles
That will not speak again of innocence.
