Burying a work of art (9)

I believe the answer is:

engraving

I'm a little stuck... Click here to teach me more about this clue!

'art' is the definition.
(engraving is a kind of art)

I don't understand the remainder of the clue.

(Other definitions for engraving that I've seen before include "Carving on hard surface" , "Cutting" , "art" , "the funeral ceremony?" , "artwork" .)

I've seen this clue in The Guardian.
