WayneLigon said:I think we can discount the Shroud of Turin, Noah's Ark, the Spear, the nails of the Cross, anything to do with Jesus having fathered children, etc, as being too well known.
I think the Spear still qualifies as esoteric to the American mass market. It has been used in certain bits of fiction of late, but those have alll been niche things, while Indy is for Everybody.
The location of the Garden of Eden would be an interesting one; the 'potentially offensive' part could be the legend that it's in the Middle East somewhere.
How does the Garden of Eden not qualify as "too well known"?
