What could illustrate The Iliad, say, from page one onwards (3)
I believe the answer is:
pic
'what could illustrate the iliad say' is the definition.
I can't tell whether this definition defines the answer.
'page one onwards' is the wordplay.
'page' becomes 'p'.
'one onwards' becomes 'ic' (I am not sure about this - if you are sure you should believe this answer much more).
'p'+'ic'='PIC'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for pic that I've seen before include "Photo (colloq.)" , "Photo (informal)" , "Snapshot" , "Photograph (colloq.)" , "Image (abbr)" .)
