A seriously strange book that I ran across back at the Ames Library was The Tamil Alphabet and its cosmic aspect by P V Manickam Naicker.
I found both a Tamil and English translation, but didn’t read it – these images were enough for me to get the gist of it, I think! The symbol for the vowel O was compared to a divine posture, the shape of internal organs, and embryos… I think it’s safe to say that there is a biased take on history in this one!
Not a great source of typographic inspiration, but interesting nonetheless, right?!
