[Rockhounds] Chabazite poem

[Kitty & Bill Heacox]

I've found the following quote about the origin of the name, chabazite, 
on several websites including mindat.  Only problem is I can't find the 
poem.  I was curious to learn what the other 19 stones were, but can't 
find <Peri lithos> with or without Orpheus.  Since Orpheus is part of 
Greek mythology, it's not like looking for a genuine poet.  Anybody have 
any ideas?

 From Gk. chabazios, tune or melody, one of twenty stones named in the 
poem Peri lithos, which extolled the virtues of minerals. The poem is 
ascribed to Orpheus.

Aloha, Kitty
