'the curiosity is satisfied and the sale has dropped...'

 In April 1817 Charles Ollier, Keats's first publisher, wrote thus to the poet's brother George: 

'Sir, – We regret that your brother ever requested us to publish his book, or that our opinion of its talent should have led us to acquiesce in undertaking it. We are, however, much obliged to you for relieving us from the unpleasant necessity of declining any further connexion with it which we must have done, as we think the curiosity is satisfied and the sale has dropped. – By far the greater number of Persons who have purchased it from us have found fault with it in such plain terms, that we have in many cases offer'd to take the book back rather than be annoyed with the ridicule which has, time after time, been shower'd on it...'

The book was Poems (1817), Keats's first publication, a volume which contains one of the greatest sonnets in the language – this:

On First Looking into Chapman's Homer

Much have I travell'd in the realms of gold,

And many goodly states and kingdoms seen;

Round many western islands have I been

Which bards in fealty to Apollo hold.

Oft of one wide expanse had I been told

That deep-brow'd Homer ruled as his demesne;

Yet did I never breathe its pure serene

Till I heard Chapman speak out loud and bold:

Then felt I like some watcher of the skies

When a new planet swims into his ken;

Or like stout Cortez when with eagle eyes

He star'd at the Pacific—and all his men

Look'd at each other with a wild surmise—

Silent, upon a peak in Darien.

Poems did initially attract a couple of good reviews, but was duly shot down by Blackwood's Magazine, largely because of Keats's association with  the enemy, i.e. Leigh Hunt. Hunt himself declared that the Chapman's Homer sonnet 'completely announced the new poet taking possession'. He was right. 
By the way, if anyone fancies owning the first edition of Poems, in its original boards, there's one on the market now for just shy of £50,000.
