Is there an edition of Keats' poem To Autumn which ends the first stanza with something other than a period (full stop)? Do we have an edition of it that Keats saw through the press?
I think the stanza ought to end with a colon but I have not seen it printed that way. It ought to end with a colon because as it stands it is merely a sentence fragment, and I have never known Keats to write sentence fragments (ejaculations are a kind of sentence); with a colon, the stanza is an extended equivalent to "O Autumn" leading up to the next stanza, which begins with a complete sentence.
