They are the ground, the books, the academes,
From whence doth spring the true Promethean fire.
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.
When daisies pied and violets blue,
And lady-smocks all silver-white,
And cuckoo-buds of yellow hue
Do paint the meadows with delight,
The cuckoo then, on every tree,
Mocks married men.
-Shakespeare, "Loves Labour's Lost"
