Who invented the type of script used in autographs?
Cuneiform script Cuneiform script ( or or ), one of the earliest systems of writing, was invented by the Sumerians. It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus. The name "cuneiform" itself simply means "wedge shaped".
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.
