I always thought linear B was associated with Crete.
Indeed it was. Arthur Evans wanted to be the one to crack the decipherment and failed. He saw to it that very little was published during his lifetime. The first tablets which showed up in his dig at Knossos he had laid out on the hillside overnight. There was rain in the night and the surfaces of those tablets were ruined, basically “no more tablets” (Wunderlich). Evans insisted that the one language that they couldn’t be was Greek.
Some years after Evans died, Carl Blegen got a permit to dig at the “Palace of Nestor” at Pylos, and in a legendary best-first-day-ever uncovered the lost city’s archive of Linear B tablets, which were published pretty quickly, and allowed Ventris et al to break the decipherment wide open despite the lack of a bilingual.
Linear B records Greek.
Linear A is Cretan. B is Mycenaean.
