At Pylos, on the very first day of excavations in 1939, Blegen and his team found the first few clay tablets from what would turn out to be a huge archive containing texts written in Linear B.
. . . a form of Bronze Age writing discovered on tablets in Crete, dating from c. 1400 to 1200 BC. In 1952, it was shown to be a syllabic script composed of linear signs, derived from Linear A and older Minoan scripts, representing a form of Mycenaean Greek.
