This is most strange,
That she, that even but now was your best object,
The argument of your praise, balm of your age,
Most best, most dearest, should in this trice of time
Commit a thing so monstrous, to dismantle
So many folds of favour.

– William Shakespeare

King Lear, Act 1, Scene 1. The King of France comments on Lear’s irrational behavior and on his former affection for Cordelia. He finds it strange that Cordelia, Lear’s "best object," should have done something so monstrous to lose that affection. France is being ironic here, for he can see clearly, if Lear cannot.
