"To one who fences or has used the broad sword a feeling for oppositional line should come as second nature. A long sweeping stroke must be parried or opposed frankly; the riposte must also be parried. A bout is a picturesque composition of two men and two minds in which unity of the whole and of the parts is preserved by the balance of opposed measures. The analogy is appropriate. The artist stands off brush in hand and fights his subject to a finish, the force of one stroke neutralizing and parrying another."
- Henry Rankin Poore, Pictorial Composition and the Critical Judgement of Pictures
