___That is pretty amazing bit of knowledge there allright on the dye. Have you ever seen the movie "The Rose", wherin monks are dying from poison ink used in the most secret books? They were licking there fingers before turning each page.
___How about the musical instrument Ben Franklin invented, the harmonium? It was made of glass spheres of different diameters revolving on a horizontal spindel & played by wetting the fingers & dragging them on the spheres to make notes. Beautiful haunting sound & even Motzart (?) composed for it. Unfortunately they were using leaded glass & all the most talented Harmoniasts died within a few years of lead poisoning. The instrument lost favor as the public came to believe it was the work of the Devil!
___The ape & mushroom idea is OK as far as it goes, but I hardly see how it ever is provable. Wine & beer require considerable more technology than eating a plant, eg vessels for fermenting. On the other hand, considerable care & expertise is in the hands of shaman who administer hallucinogens. Nothing like understanding everything & at the last moment also that you've killed yourself.

(What? No mushroom emoticon?)GETE
