To Nobodaddy
by William Blake

Why art thou silent & invisible,
Father of Jealousy?
Why dost thou hide thyself in clouds
From every searching Eye?

Why darkness & obscurity
In all thy works & laws,
That none dare eat the fruit but from
Thy wily serpent's jaws?
Or is it because Secrecy
Gains females' loud applause?
