[The King of Navarre's park.]

Biron:

But love, first learned in a lady's eyes,
Lives not alone immured in the brain,
But with the motion of all elements
Courses as swift as thought in every power,
And gives to every power a double power
Above their functions and their offices.

It adds a precious seeing to the eye —
A lover's eyes will gaze an eagle blind.

A lover's ear will hear the lowest sound
When the suspicious head of theft is stopped.

Love's feeling is more soft and sensible
Than are the tender horns of cockled snails.

Love's tongue proves dainty Bacchus gross in taste.

For valour, is not love a Hercules,
Still climbing trees in the Hesperides?

William Shakespeare
Love's Labour's Lost, 4.3.301-315
