I just read the lyrics to woad in the data base. I'd like to point out that woad is a mild narcotic. This being the case, the tradition of a plying it in decrative paturns that just hapen to intersect all the points at wich vains and arteries are near the surface of the skin may have contributed greatly to the celts reputation for being biserk warriors. I have this info on the athourity of a sca squire who is very good at telling antidotes about drunken parties, and makeing them sound interesting. So you can take that for what its worth.
