Men of the Renaissance with long teaching experience? (3,7)
I believe the answer is:
old masters
'men' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's an association between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for old masters that I've seen before include "Art's models (anag) - classic painters" , "Great Renaissance paintings" , "Classic artists" , "experienced in school?" , "Great works" .)
