Where the bright phœnix loves to rest

A raven’s egg—and mark it well,

When the vile bird has chipped its shell,

Though fed with grains from trees that grow

Where Salesbel’s[[236]] sweetest waters flow—

Though airs from Gabriel’s wings may rise

To fan the cradle where he lies;

Though long these patient cares endure,

It proves at last a bird impure.
