The poem
This lunar beauty Has no history Is complete and early, If beauty later Bear any feature It had a lover And is another.
This like a dream Keeps other time And daytime is The loss of this, For time is inches And the heart's changes Where ghost has haunted Lost and wanted.
But this was never A ghost's endeavor Nor finished this, Was ghost at ease, And till it pass Love shall not near The sweetness here Nor sorrow take His endless look.
When Jim Holt decided to start memorizing poetry (See Essay in the NY Times Book Review, April 5, 2009, p.23) he started with this poem. I never read it before but it is a lovely poem to read aloud.
