Fairy: “The cowslips tall her pensioners be:

In their gold coats spots you see:

Those be rubies, fairy favours,

In those freckles live their savours.

(A Midsummer Night’s Dream, Act II, Sc. 1.)

Macbeth: “You make me strange

When now I think you can behold such sights,

And keep the natural ruby of your cheeks,

When mine is blanched with fear.

(Macbeth, Act III, Sc. 4.)
