Prime - other examples --- In found in my "Brewer. The Dictionary of Phrase & Fable", Wordsworth Reference, 1993, other two examples.

Prime: In the Catholic Church the first canonic hour after lauds. In Paradise Lost, Milton terms sunrise 'that sweet hour of prime'.

Primed: Full and ready to deliver a speech. We say of a man whose head is full of his subject. "He is primed to the muzzle." Of course, the allusion is to firearms. [sic!]
