Egyptian god of the dead (6)
I believe the answer is:
osiris
'egyptian god of the dead' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for osiris that I've seen before include "Egyptian god of the dead" , "Husband of Isis, father of Horus - sis or I (anag)" , "once highly esteemed by Egyptians" , "one held to be divine" , "Egyptian deity" .)
