Damn shame I followed Deep's original link - which includes that image of the gates - and read The New Yorker's article after searching for images about the temple's gates - which includes that image of the gates.
Doesn't matter really...I am satisfied that the original article was a cut down of The New Yorker's article, with speculations that are incorrect...just silly me took the image and wondered about the fleur de lis; the temple's time period of construction, treasure and use; and the Templar Knights.
Diamond Dao mind.
Bring forth this indefinitely continuing existence;
The infinitesimal feeds the infinite and ages this ouroboros of mine."
