In the past, those who have looked for linguistic patterns in Linear A by comparing inscriptions from different parts of Crete have been met with a common objection: “How do you know Linear A encodes the same language across the island?” In Chapter 7, Crete is divided into five regions centered around the five main Minoan palaces, and the corpus of Linear A is likewise divided into five corpora, each containing the inscriptions from a single region. These five corpora are analyzed against each other in an effort to answer this question. As a control, five analogous corpora of Linear B inscriptions are analyzed against each other in the same way, with the results demonstrating an overwhelming probability that they all encode the same language (which we know they do, as this script is deciphered: all Linear B inscriptions encode Greek). The analysis of the Linear A corpora demonstrates a similarly overwhelming probability that Linear A encodes the same language everywhere in Crete. The Linear A and B corpora are also analyzed against each other, demonstrating an overwhelming probability that the two scripts encode different languages—that is, that Linear A does NOT encode Greek.
