Analysis of The Unexpressed

How dare one say it?
After the cycles, poems, singers, plays,
Vaunted Ionia's, India's -Homer, Shakespeare -the long, long times, thick
dotted roads, areas,
The shining clusters and the Milky Ways of stars -Nature's pulses reaped,
All retrospective passions, heroes, war, love, adoration,
All ages' plummets dropped to their utmost depths,
All human lives, throats, wishes, brains -all experiences' utterance;
After the countless songs, or long or short, all tongues, all lands,
Still something not yet told in poesy's voice or print -something lacking,
(Who knows? the best yet unexpressed and lacking.)
