In a private message to me from Michel he had thought that the
Noble Eightfold Path could be reproduced in some kind of durable medium. I think it is a good idea. Perhaps the GWV will consider a reproduction of the Noble Eightfold Path in some kind of durable medium, and market it, or give it away, if there is sufficient funding to do so.
Durable media:
Platinum, gold, silver, copper, bronze, brass, beryllium, quartz, cut stone, ceramics, fire bricks, archival papers.
The precious metals: Platinum, gold, silver, are certainly durable, but all too easily stolen and melted down; nonetheless, the wealthy are inclined to purchase and reserve a plaque made from one of these metals.
Cut stone is certainly durable; however, it is commonly taken from one building and used to construct another one. Nonetheless, it could be attractive to the wealthy in a monumental art piece that could stand up against erosion for 10s of thousands of years.
The engineering metals: copper, bronze, brass, beryllium, quartz, are very durable, but have sufficient value that they are likely to be turned into something else later. Nonetheless, the middle classes are inclined to purchase and reserve a plaque made from one of these metals.
Ceramics are very durable, and have no real intrinsic value, so they are likely to reside undisturbed in the archaeological record for 10s of thousands of years.
Fire brick is durable, but does not standup well to abrasion. They are also not fine enough grain for detailed work, such as is required for language.
Archival papers are within the means of the poor, are easily reproduced, and can last for thousands of years if carefully preserved in a ceramic jar in a cave undisturbed.
