Comic mostly promoting European's first appearance as Shakespearean prince (8)
I believe the answer is:
pericles
'prince' is the definition.
(I have seen 'Prince of Tyre ' mean 'pericles' so perhaps 'prince' could also mean 'pericles')
'comic mostly promoting european's first appearance as shakespearean' is the wordplay.
I cannot quite understand how this works, but
'european's' could be 'es' (abbreviation e.g. EU) and 'es' is located in the answer.
'first' could be 'i' (Roman numeral for one or first) and 'i' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pericles that I've seen before include "Statesman in Athens" , "Ceps rile up the Athenian who ordered the construction of the Parthenon" , "Shakespeare play '......., Prince of Tyre'" , "Ancient Athenian leader - prince of Tyre" , "Athenian statesman" .)
