Yes, I remember the original rituals. King missed this and that and the other, but it was pretty close, and there are far more accurate versions floating around. Since I agree with you about the virtue of conservation, and since, strictly speaking, none of these rituals are the same as present rituals, conservation of the originals is of paramount importance, as was true of the conservators of Memphis-Misraim and many other dead or dying rites.

Ah, but the secret is in the music. That's the real OTO? ;-]
