'T is slander,
Whose edge is sharper than the sword: whose tongue
Outvenoms all the worms of Nile; whose breath
Bides on the posting winds, and doth belie
All corners of the world,--kings, queens, and states,
Maids, matrons,--nay, the secrets of the grave
This viperous slander enters.
SHAKS.: _Cymbeline,_ Act iii., Sc. 4.
