[Kuruharan]

A reference to Rohirric beliefs here. The Rohirrim apparently are ancestor worshippers. Theoden will go to be with his ancestors, whose opinion & judgement on his actions is important to him. He has had standards to live up to which he feels he has finally lived up to. He has achieved the fame necessary to stand in their company. The interesting thing is that he seems to feel that his 'fathers' still 'live' in some form, in some other 'place'. Is this some place of their own invention? Have they picked up a belief in the Valar through their contact with Gondor, or is this a survival of older beliefs they brought south with them?

Thorin says something very similar at his death. The Rohirrim may have picked it up from the dwarves in the days when they lived up north. They also had extensive contact with Gondor even before they went north so both...perhaps.

However, I think "worship" is far too strong a word for it. "Respect" might be a better term. Just because you desire the good opinion of somebody does not mean that you worship them (even if they are dead.)
