Hmm...does this item have to do with the graffiti thought to have been the work of Bedouins during the middle ages or is this item from the new Kingdom era?

The originals were New Kingdom.

The court with a brick wall with proto-Doric columns forming a rear portico??????

No - I do not have a plan but it could be involved in 1 of the items you mentioned.
As an aside were Doric columns inspired by Egyptian Proto-Doric columns?
I have heard that Greek sculpture was originaly inspired by Egyptian originals.

Just looked at the plan. On my plan it is argueable whether the items are in the court.
Neither of my AVM questions are about things that are solely Egyptian though in AVM-2 the thing would be noticably different if it were not Egyptian.

hey threes,
I guess that if you wish to rule this game, you should invent something more...(how can I say?) ACTIVE?

You can see the items when you approach the temple. Most of the ones you see are modern replacements.
