'On its hinge'
“An agitation of the air,
A perturbation of the light
Admonished me the unloved year
Would turn on its hinge that night.’’
— From “End of Summer,’’ by Stanley Kunitz (1905-2006). The Worcester native was a celebrated poet and teacher who for much of his later life moved back and forth between homes in New York City and Provincetown. The autumn equinox comes on Tuesday, Sept. 22, this year.
