bilby commented on the word variance
"Well said, then this is thy trial: Instead of carrying
the King's letters to my father, carry thou these letters to my
sister, which contain matter quite contrary to the other:
there shall she be given to understand, that my father hath
detracted her, given out slanderous speeches against her; and
that he hath most intolerably abused me, set my Lord and
me at variance, and made mutinies amongst the commons."
- anon., 'King Leir'.
