The oldest inscriptions, preserved on bone tablets and pottery vessels
      dating back to Dynasty 0 (the end of the 4th millennium B.C.), recorded
      names of the rulers, toponyms and names of products [
01].
      Hieroglyphs [
02], as well
      as the hieratic and demotic - cursive forms derived from them, remained
      in use until the first centuries A.D. and served to note down texts of
      highly varied nature - from monumental inscriptions on temple or tomb walls,
      through papyrus documents [
03],
      up to memoranda and receipts recorded on ostraca [
04].
      The god Thoth, the mythical inventor of writing presented as an ibis or
      a baboon, was the patron of Egyptian intellectuals [
