Ancient artifacts (6)
I believe the answer is:
relics
'ancient artifacts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for relics that I've seen before include "all that remain" , "Venerated pieces of saints" , "Venerated remains" , "Surviving traces or holy pieces" , "Parts of holy person's body or belongings" .)
