Yes m_m there certainly should be a connection between Chongoni Rock Art and Masterpieces of Oral and intangible Heritage via Gule Wamkulu!!
This is not mentioned in the current UNESCO entry for the inscribed site BUT the old T List entry (which somewhat surprisingly still remains in place!) specifically refers to the link (last sentance of "description")http://whc.unesco.org/en/tentativelists/916/
Quite why these words in the T List description were not carried forward to that of the inscribed site isn't clear to me - I can't see that it was due to any reduction in the inscribed area. And the link to Gule Wamkulu is only indirectly referred to in the Advisory Body Evaluation via its references to the nyau
secret society. But perhaps I am too ready to look for hidden motivation in what UNESCO etc do and do not do! There is a fine English phrase concerning why "unexplainable" things happen - "Conspiracy or cock up"!
There are other Web links too which clarify the connection. E.g. search on Chongoni within this PDFhttp://www.nomadic-adventures.net/assets_d/4238/portfolio_media/letter_from_malawi-fi nal-edit.pdf
Specific places mentioned in this article e.g Chentcherere and Mphunzi are identified on the map within the Chongoni evaluation. I have been planning a visit to Malawi and it was interesting that the company I have been dealing with didn't seem to have taken anyone to Chongoni - but was prepared to take me - though i would want to sort out "local permission" issues. The Article mentions that the increasing numbers of visitors has actually reduced the traditional value of the sites. Unfortunately the author doesn't seem to state exactly where he saw the Gule Wamkulu - though he does establish a strong link between it and sites within the inscribed area.
PS It occurs to me that it ought to be possible to identify a connection for "Secret Societies" - Chongoni/Nyau
gives us 2 straight away. There could be a few definitional problems though - e.g are the Jesuits a "Secret Society"? But they already have their link so perhaps we could have a connection of "secret societies not connected specifically elsewhere". There ought to be a number of "western" sites connectable to Freemasonry and if enough were found perhaps it would justify a separate link. In the mean time putting Masons in with other (e.g African) Secret Societies then Monticello will provide the 3rd Connection. I thought I remembered a potential masonic aspect for Jefferson from my long past American history studies - seehttp://wiki.monticello.org/mediawiki/index.php/Freemasonry
PPS. Another Masonic connection -
