Assuredly, no genius just as sure!

Safe mediocrity had scorned the lure

Of now too much and now too little cost,

And satisfied me sight was never lost

Of moderate design's accomplishment

In calm completeness. On and on I went

With no more hope than fear of what came next,

Till lo, I push a door, sudden uplift

A hanging, enter, chance upon a shift

Indeed of scene! So—thus it is thou deck'st
