Echo possibly roused about Narcissus's face (7)
I believe the answer is:
resound
'echo' is the definition.
(I know that echo can be written as resound)
'roused about narcissus's face' is the wordplay.
'about' indicates anagramming the letters.
'face' suggests taking the first letters.
The first letter of 'narcissus' is 'n'.
'roused' mixed up with 'n' gives 'RESOUND'.
'possibly' is the link.
(Other definitions for resound that I've seen before include "Echo" , "Reverberate" , "ring" .)
