Sergeant
RALPH: Quarry derives from the old French word, cuiriee, the hide of an animal. Originally, quarry meant the worthless parts of an animal killed on a hunt--like the entrails--which were given to the hounds as their reward.
DAVINA: Later, quarry came to mean any group of dead corpses, either animals killed during a hunt, or soldiers slain on the battlefield. Later still, it also came to mean the animal which you were pursuing on a hunt.
RALPH: In this line, Shakespeare uses both of these last two meanings of the word. In the first sense, Fortune is smiling on Macdonald’s quarry, referring to all of the soldiers Macdonald has killed. In the second sense, Fortune is hunting Macdonald, making him its next intended victim.
