Messing in Meter
Messing about with rough text, then metered it into dialogue, then for interestingness. It's not the material or idea but what you do to it.

hard by her, on either hand pretty fair boys appareled as painters do set forth god Cupid, with little fans in their hands, with which they fanned wind upon her.
On ei|ther hand |were pret|ty boys | ap-par-eled
As if |they each |were Cu|pid, fan|ning her
To keep |the wind |up-on | her.
On either side stood sweating boys
Like Cupidons with multi-colored wings
They teased the air with fans
That almost robbed the swooning breeze…
