Ancient poet runs wearing watch (6)
I believe the answer is:
virgil
'ancient poet' is the definition.
'virgil' can be an answer for 'poet' (I've seen this before). I am not sure about the 'ancient' bit.
'runs wearing watch' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'wearing' is an insertion indicator.
'watch' becomes 'vigil' (to keep vigil is to keep watch).
'r' placed into 'vigil' is 'VIRGIL'.
Can you help me to learn more?
(Other definitions for virgil that I've seen before include "Latin poet" , "old poet" , "Author of the Aeneid, d. 19 BC" , "Roman poet who wrote the Aeneid" .)
