Mythical matchmaker (4)
I believe the answer is:
eros
'mythical matchmaker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eros that I've seen before include "Sore about love god" , "Greek love-god" , "Roman god of love, Cupid" , "Pagan god" , "Form of love" .)
