(To). To lower; to cast down. Brutus complained that he had not lately seen in Cassius that courtesy and show of love which he used to notice; to which Cassius replies, “If I have vailed [lowered] my looks, I turn the trouble of my countenance merely on myself. Vexed I am of late ... [and this may] give some soil to my behaviour.”
His hat, which never vailed to human pride, Walker with reverence took and laid aside.
