'character played part' is the definition.
'role' can be an answer for 'character' (I've seen this before). I'm unsure of the 'played part' bit.

'of prospero legendary' is the wordplay.
'of' says the answer is hidden in the clue.
'ROLE' is hidden within 'prospero legendary'.

Can you help me to learn more?

(Other definitions for role that I've seen before include "Playing part" , "Duty" , "Function; part" , "Stage part" , "Character" .)
