Seek through this grove.
A sweet Athenian lady is in love
With a disdainful youth; anoint his eyes,
But do it when the next thing he espies
May be the lady. Thou shalt know the man
By the Athenian garments he hath on.
Effect it with some care, that he may prove
More fond on her than she upon her love.
– William Shakespeare
A Midsummer Night’s Dream, Act 2, Scene 1. Oberon takes pity on Helena, who is not having luck in love in her pursuit of the reluctant Demetrius. The Fairy King instructs his servant Puck to anoint Demetrius’ eyes with the magic flower potion that that he will fall in love with Helena.
