I do not know
One of my sex; no woman’s face remember,
Save, from my glass, mine own; nor have I seen
More that I may call men than you, good friend,
And my dear father: how features are abroad,
I am skilless of; but, by my modesty,
The jewel in my dower, I would not wish
Any companion in the world but you,
Nor can imagination form a shape,
Besides yourself, to like of.

– William Shakespeare

The Tempest, Act 3, Scene 1. Miranda did not see many faces of people during her life on the island, as she was living there alone with her father and Caliban since she was a little girl. She swears by her virginity – "the jewel in my dower" – that she does not wish for any other companion in the world than Ferdinand.
