Clay tablet


Small tablets made out of clay were used from 5500 BC Tărtăria tablets and later from 4th millennium BC onwards as a writing medium in Sumerian, other Mesopotamian, Hittite, and Minoan/Mycenaean civilizations. The Tărtăria tablets of the Danubian civilisation may be older still, having been carbon dated to before 4000BC, but their interpretation remains controversial. Sumerian cuneiform characters were engraved on the tables using a stylus. Later the tablets were left to dry or even fired in a kiln.
