A quietness distilled As twilight long begun, Or nature spending with herself Sequesteredº afternoon. ºkept secret and secluded
The dusk drew earlier in, The morning foreign shone - A courteous, yet harrowingº grace, ºagonizing As guest who would be gone.
And thus, without a wing Or service of a keelº, ºto collapse or fall Our summer made her light escape Into the beautiful
Okay, my question is, what does "the morning foreign shone" means?
