If the first two articles on Linear B can be considered a starting point, pointing out a new research direction, then Leonard Ethan's third article begins the detailed study of Linear B.
The core content of the third thesis is to list the vowels and consonants, which is an essential step in translating those phonetic characters. Then, a table similar to the Japanese 50-sound chart was created.
Of course, this table is just a framework, and the vowels and consonants do not have actual values. It only gives the relationship between these syllables.
However, this is already the most important step in deciphering Linear B. The actual decipherment now only requires completing this table and assigning values to these syllables.
