On this day in 1952, 65 years ago, Michael Ventris made the announcement that he had deciphered Mycenaean Linear B. Against all expectations, he had discovered that these Late Bronze Age documents were written in Greek – making them some 400 years earlier than any other known Greek inscriptions.
The announcement was made on the radio, and luckily the recording still survives. You can hear it HERE in a post made by the BBC a few years ago.
You can read more about the decipherment process HERE in a resource made available by the Cambridge Mycenaean Epigraphy Group.
