Virgilian poem snubbed last king in command (7)
I believe the answer is:
georgic
'virgilian poem' is the definition.
'georgic' can be an answer for 'poem' (thesaurus). I am not sure about the 'virgilian' bit.
'snubbed last king in command' is the wordplay.
I cannot really understand how this works, but
'king' could be 'r' (abbreviation for rex, king in Latin) and 'r' is found within the answer.
'in command' could be 'ic' (military abbreviation) and 'ic' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for georgic that I've seen before include "pastoral!" , "A farming poem" , "work on fields?" , "agricultural book" .)
