Ancient artefact and Villa's location protected by political favour? (7,5)
I believe the answer is:
rosetta stone
'protected by political favour?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'ancient artefact and villa's location' is the wordplay.
I cannot really see how this works, but
'artefact' could be 'set' (set is a kind of artefact) and 'set' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
