The border between prehistoric and historical societies is the domain of writing. Until today they have only come written clay tablets, with remains of linear writing A and remains of linear writing B, although it is believed that it was written on other material that has not reached until today, or that has not yet been found. The original writing materials are thought to have been papyri or parchment. It is also believed that the clay was a temporary support to later pass the writings to the other materials, but the fires destroyed everything, at the same time they baked the clay tablets and thus these writings could reach today.
When meeting clay tablets, stamps and gaffitis, it is seen that Minoan society used writing.
The archaeologist Arthur Evans called this succession of ideograms cretan hieroglyphs, and until today they have not been deciphered, but it is believed that they are from the year 2.000 to 1.600 BC
There is also a second syllabic system, Linear A within the years 1.900 to 1.450 BC, which had 75 different signs that have yet to be deciphered. It is thought that if some day these scriptures are deciphered, they may not be understood.
From this writing the linear system B is derived only in Knossos, dated between 1.450 and 1.400 BC, these writings could only be read in 1953, and it was possible to know in 1956 that it is a prehistoric greek dialect they used in Mycenae, but could not survive.
They were only administrative writings, inventories, censuses, counts of herds and crops, they had neither literary nor religious use, according to the tablets discovered in 1939 in Pylos and in Mycenae in 1952.
