Famous Italian represented cardinal on video (8,2,5)
I believe the answer is:
leonardo da vinci
'famous italian' is the definition.
(I've seen this before)
'represented cardinal on video' is the wordplay.
'represented' indicates an anagram.
'cardinal'+'on'+'video'='cardinalonvideo'
'cardinalonvideo' anagrammed gives 'LEONARDO DA VINCI'.
(Other definitions for leonardo da vinci that I've seen before include "He painted" , "Renowned painter" , "artist ..." , "famous Italian" , "Mona Lisa painter" .)
