Our reading
An editorial interpretation.
The speaker laments that something rotten can be wrapped in beauty, comparing a deceitful person to a handsomely bound book with vile content, and a lavish palace hiding dishonesty. The passage is about the painful gap between attractive outward form and ugly inner truth.
