Dynasty celebration recalled deity (3,3)
I believe the answer is:
sun god
'deity' is the definition.
(sun god is a kind of deity)
'dynasty celebration recalled' is the wordplay.
'dynasty' becomes 'Sung' (Chinese dynasty).
'celebration' becomes 'do' (I've seen this in other clues).
'recalled' shows that the letters should be reversed in order (to recall can mean to bring something back).
'do' in reverse letter order is 'od'.
'sung'+'od'='SUN-GOD'
(Other definitions for sun god that I've seen before include "Amen-Ra" , "RA" .)
