This is a very early writing system that predates the Greek alphabet. There has been extensive studies to understand this pre alphabet in both Crete and Cyprus. Knossos is a very important historical site in Crete where these tablets have been discovered on archeological digs.
On Cyprus lectures are given about its importance about its role as a precursor to the Greek language. These lectures are given in Greek at the university of Nicosia in Cyprus but I was able to find out about it because the lecturer is in fact English. There was a magazine article I read about his work and how he came to learn the Greek language over a period of approximately 30 years. I found it fascinating that there is still much to learn about prehistoric times because the information was either recorded in a language that is now indecipherable to us; or was just passed down verbally as they had no means of remembering things in terms of texts.
Linear B is a written language that is in itself predated by Linear A which hasn’t been decoded yet. Linear B was uncovered by English architect Micheal Ventris. He was a Classist and self taught linguist. His specialty was the Mycenaean era of Greece. He sadly died in a car crash very early on in his life otherwise this new field could be much further forward than it is today.
