Wide-ranging, thorough and delightful, including a comparison of Firbank with James Joyce (!), the piece is well worth perusing even if you're not a fan of Firbank's purple prose. Which, honesty compels me to say, none of us was, though most of us were glad for the opportunity to read this work.
That said, I do subscribe to Cooper's assessment:
"Firbank is with doubt a minor writer (whether Joyce, for all his present 'reclame', is a major one, is a question which can only be settled by posterity), but one who, for the most part, achieved precisely what he set out to do."
