"And Fortune on his damned quarry smiling."
Holinshed, treating of this very matter, says, "to assist him in that rebellious quarrel." Hence the usual correction of quarrel for 'quarry' seems to be justified. In the old writers quarrel in the sense of cause, party, is frequent. It was in ordinary use at that time, alike in French and English.
"Like Valour's minion, carv'd out his passage,
Till he fac'd the slave ***"
We might add, with Vengeance at his side.
"Shipwrecking storms, and direful thunders break."
So Pope, from breaking of the 2nd folio.
