Martin came up with the idea of using something like the roots from semitic languages for naming things. I thought of the same before I read this article, but it's good to have it written down by somebody.

Collection of encrypted correspondence between the compiler and various correspondents, in approximately 150 alphabets, accompanied by transcriptions of the letters in Arabic. The compiler cites Shihāb al-Dīn al-Jindī al-ʻAlāʼī, Burhān al-Dīn al-Qudsī, and Taqī al-Dīn Muḥammad ibn Jaʻfar al-Ḥusaynī as authorities for some of the alphabets. The manuscript is incomplete, lacking its beginning and end. Occasional marginal notes. Some worm damage in margins.
