California allows the COR, and it is codified, but in my opinion, it has been so sanitized as to defeat the purpose.
Some of the original CORs incorporated symbols from well outside of Masonry (alchemical and astrological to name a few) as well as inscriptions in Latin. There was a time when the brothers joining were highly educated and would have recognized these symbols and understood their purpose and how it related to their preparation for initiation. Those days are gone. Having alchemical symbolism in the COR now serves only to make it seem more occult than it is and doesn't really contribute anything. At the same time, California goes so far as to remove the skull (in my opinion, the second or third most important item in the COR and one that can easily be understood). Unless a lecture was added to the degree (fat chance of that happening) explaining some of the symbolism (V.I.T.R.I.O.L. to me is not only beautiful, but a very clever play on words once you understand it) then I thing that anything being inscribed on the walls ought to be in the native language (in our case, English), on the table ought to be the skull, a mirror, a candle, a pen, and a sheet of paper, and that's it.
Of course, that's just my opinion, which, added to $7, might get you a cup of over roasted coffee.
