Who invented the type of script used in autographs?
Autograph (Assyriology) An autograph in Assyriology is the hand-copy of a cuneiform clay-tablet. Producing an autograph is often the first step of a tablet's archaeological interpretation and the autograph is frequently the authoritative form that is published as source material. Autographing the text is followed by transliteration, transcription and translation.
Siddhaṃ script Siddhaṃ , also known in its later evolved form as Siddhamātṛkā, is the name of a script used for writing Sanskrit from c. 550 – c. 1200. It is descended from the Brahmi script via the Gupta script and later evolved into the Assamese alphabet, the Bengali alphabet, and the Tibetan alphabet. There is some confusion over the spelling: "Siddhāṃ " and "Siddhaṃ " are both common, though "Siddhaṃ " is preferred as "correct". The script is a refinement of the script used during the Gupta Empire.
