Fantasia bathers (8)
I believe the answer is:
centaurs
'fantasia bathers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for centaurs that I've seen before include "Man-horses?" , "Fabulous beasts of Etruscan origin" , "Tan curse on the mythical creatures" , "'Mythical creatures, half-man, half-horse (8)'" , "Mythical creatures, half man and half horse" .)
