Usage examples:

And Thomas Heywood, in 1612, thus writes in defence of the actor's art: Tully, in his booke, 'Ad Caium Herennium, ' requires five things in an orator- invention, disposition, eloqution, memory, and pronuntiation; yet all are imperfect without the sixt, which is action: for be his invention never so fluent and exquisite, his disposition and order never so composed and formall, his eloquence and elaborate phrases never so materiall and pithy his memory never so ferme and retentive, his pronuntiation never so musical and plausive; yet without a comely and elegant gesture, a gratious and a bewitching kinde of action, a natural and familiar motion of the head, the hand, the body, and a moderate and fit countenance suitable to all the rest, I hold all the rest as nothing.
