Like an arrow shot

From a well-experienc'd archer hits the mark

His eye doth level at.

William Shakespeare (1564-1616): Pericles. Act i. Sc. 1.

Let still the woman take

An elder than herself: so wears she to him,

So sways she level in her husband's heart:

For, boy, however we do praise ourselves,

Our fancies are more giddy and unfirm,

More longing, wavering, sooner lost and worn,

Than women's are.

William Shakespeare (1564-1616): Twelfth Night. Act ii. Sc. 4.
