Glagolitic alphabet 

This article states that the Glagolitic alphabet was *devised* by C & M.  However, the Wiki page on Glagolitic alphabet (http://en.wikipedia.org/wiki/Glagolitic_alphabet) contradicts this statement by saying that the Glagolitic alphabet pre-existed the arrival of C & M.  I think that, at most, we can say that C & M REvised (not DEvised) the alphabet to include sounds for the Slavic language.
