Linear A and BThe Decipherment

Alice Kober's Triplets

In the 1940s Alice Kober showed that Linear B words change their endings, using sets of three related forms, without guessing any sounds.

With the signs numbered (Numbering the Signs) and a grid in mind (How a Syllabary Works), you are ready for the first great step. It was taken in New York in the 1940s by Alice Kober, a classics professor at Brooklyn College, working in her spare time on a script nobody could read.

Key idea

Kober showed, without guessing a single sound, that Linear B words change their endings. In sets of three related forms she found signs that must share a consonant, and others that must share a vowel. Her method was to avoid guessing.

Kober's method

Kober (1906 to 1950) refused to guess what language the tablets were in. Others had tried to "read" Linear B as Etruscan, Hittite and other languages, and every guess had failed. She studied the signs as shapes instead, keeping thousands of hand-written index cards: which signs came together, which began or ended words, how often each appeared. In papers from 1945 to 1948 she showed that the language had endings that changed with grammar, as Latin and Greek do.

A triplet

Kober noticed sets of words that shared a beginning and differed at the end, in three forms. Here is a set of that kind, written with the values we know today (Kober had no values; she saw only the shapes):

Knossos, Knossian (masculine), Knossian (feminine). The third sign changes from form 1 to forms 2 and 3.

1𐀒𐀜𐀰ko-no-so
2𐀒𐀜𐀯𐀍ko-no-si-jo
3𐀒𐀜𐀯𐀊ko-no-si-ja

Look at the shapes only. Forms 2 and 3 share three signs and then differ in the last one. Form 1 has the same first two signs but a different third sign. Kober reasoned: the stem ends in a consonant. In form 1 that consonant is written together with one vowel; in forms 2 and 3 with another. So the third sign of form 1 and the third sign of forms 2 and 3 share a consonant (today we know: so and si, both s). And the last signs of forms 2 and 3 share their own consonant (jo and ja, both j) while differing in vowel.

Form 1 of the set. Compare its third sign with the third sign of ko-no-si-jo.

Why it works

Why do the "bridging" signs prove a shared consonant? In a syllabary every sign ends in a vowel. If a stem ends in a consonant, that consonant cannot stand alone; it must be written with whatever vowel follows it. When the ending changes, the vowel changes, so the scribe has to switch to a different sign with the same consonant. The switch exposes a pair of signs in the same row of the grid.

Common mistake

Thinking Kober guessed at sounds or a language. She did the opposite: she proved relationships between signs from patterns alone. Check: her results say "these two signs share a consonant", never "this sign is s". The sounds came after her death, from Ventris.

In 1948 Kober drew a small grid of ten signs showing which shared a consonant and which shared a vowel. She died in May 1950, at 43, two years before the decipherment. John Chadwick later judged her work the most valuable before Ventris's.

Worked example: Find the bridge

Three forms share a stem: Word 1 ends in sign X; Words 2 and 3 have sign Y where Word 1 has X, then one more sign. Which two signs share a consonant?
  1. The stem ends in a consonant, written with a different vowel in Word 1 than in Words 2 and 3.
  2. So the sign at that spot in Word 1 (X) and in Words 2 and 3 (Y) must share that consonant.

Answer: X and Y.

Worked example: With values

In ko-no-so and ko-no-si-jo, which signs share a consonant because of the changing ending?
  1. The third signs differ: so in one, si in the other.
  2. Both begin with s, the end of the stem Knos-.

Answer: so and si.
