NO NEED TO GILD

"Therefore to be possess'e with double pomp,
To guard a title that was rich before,
To gild refined gold, to paint the lily,
To throw perfume on the violet,
To smooth the ice, or add another hue
Unto the rainbow, or with taper-light
To seek the beauteous eye of heaven to garnish,
Is wasteful and ridiculous excess."
Salisbury, in Shakespeare's King John, 1595.
