Prelate keeps a set of books similar to some poetry (7)

I believe the answer is:
dantean
'prelate' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'a set of books similar to some poetry' is the wordplay.
'set of books' becomes 'NT' (New Testament).
'similar' becomes 'ean' (I can't explain this - if you can you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'some' means to look at the middle letters.
'poetry' becomes 'ode' (ode is a type of poem).
The central letter of 'ode' is 'd'.
'a'+'nt'+'ean'='antean'
'antean' put after 'd' is 'DANTEAN'.
'keeps' acts as a link.
Can you help me to learn more?
(Other definitions for dantean that I've seen before include "in style of Italian poet" , "like poet" , "like some Italian poetry" , "from hellish work" , "lover of poetry" .)
