Beach

Try and find the metaphor! (S)he who finds it, receives 500 gp!

Once I went a-walkin'
Down shores of golden sand
And there I saw a sight,
That made my heart expand.

The thing that left me breathless,
Driv'n to sigh and swoon
An eagle flying high above,
twixt the sea and moon

An ordinary eagle?
Nay, fly they not at night.
Nor have they from feathers
Shooting bands of light.

At times soft, sometimes not,
Colorful beams did shine,
Twixt those golden feathers,
creating beauty d'vine

"Aha!" thought I to self,
"A rainbow birth!" I breathed
For I'd discerned the truth,
As I this sight perceived.
