changing fashions

Since Robert Frost, the poets' realm's grown small
their library's contracted to one shelf.
Where Milton sang of Eden, and the Fall,
the Modern's world's no bigger than herself.
Miranda craved an Art that's got more range
let haiku-masters keep theirs neat, and terse.
While others whine, he'll engineer the change;
this generation's primed for rhyming verse.
Millennia, t'was poets ruled the stage,
from ribald comic highs, to tragic lows.
His Hamilton's the wonder of the age,
eclipsing treatments done in plodding prose.
Each year, some forms gain favor, some forms lose.
Who knows what offerings may please the Muse?
