Parliament rising to support Ireland's premier epic work of literature (5)
I believe the answer is:
iliad
'literature' is the definition.
(I've seen this before)
'parliament rising to support ireland's premier' is the wordplay.
'parliament' becomes 'dail' (Dail Eireann, Irish parliament).
'rising' says the letters should be written backwards (going up in a down clue).
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'premier' suggests taking the first letters.
The initial letter of 'irelands' is 'i'.
'dail' reversed gives 'liad'.
'liad' put after 'i' is 'ILIAD'.
'epic work of' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for iliad that I've seen before include "Greek epic poem about the Trojan War" , "story of Mediterranean heroism" , "Epic poem attributed to Homer" , "No short tale" , "City investment story" .)
