"As all mirth triumphs, sadness means defeat:
Lust triumphs and is gay, Love 's triumphed o'er
And sad: but Lucio 's sad. I said before,
Love 's sad, not Lucio; one who loves may be
As gay his love has leave to hope, as he
Downcast that lusts' desire escapes the springe:
'T is of the mood itself I speak, what tinge
Determines it, else colorless,—or mirth,
Or melancholy, as from heaven or earth."
"'Ay, that's the variation's gist!'
