In his book on ancient literacy, Reading and Writing in Babylon, the French assyriologist Dominique Charpin quotes a letter by a scribe called Hulalum that hints at silent reading in a hurry. Apparently, Hulalum switched between “seeing” (ie, silent reading) and “saying/listening” (loud reading), depending on the situation. In his letter, he writes that he cracked open a clay envelope – Mesopotamian tablets came encased inside a thin casing of clay to prevent prying eyes from reading them – thinking it contained a tablet for the king.
