Legendary king with the golden touch (5)
I believe the answer is:
midas
'legendary king with the golden touch' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for midas that I've seen before include "my gift turned out a curse" , "Legendary king whose touch turned things to gold" , "I'm sad (anag) -- king of Phrygia" , "His touch made gold" , "Mythical king who had the power to turn everything to gold" .)
