I hunted down a misquote ("Beware the wrath of patient men") that was quoted in a piece linked at American Digest, and learned that it was from a Dryden epic, possibly a satirical one, Absalom and Achitophel.
John Dryden was the literary giant of his time. He influenced many, especially Pope, and knew Marvell and Milton. Never read any Dryden - just one of countless holes in my education.
The fragment goes like this:
Oh that my Pow'r to Saving were confin’d:
Why am I forc’d, like Heav’n, against my mind,
To make Examples of another Kind?
Must I at length the Sword of Justice draw?
Oh curst Effects of necessary Law!
How ill my Fear they by my Mercy scan,
Beware the Fury of a Patient Man.
Lots of Dryden fragments and quotes here to get a sense of his clear, forceful style. He liked heroic couplets.
