Linear A and BThe Decipherment

Numbering the Signs

Emmett Bennett sorted the signs into a standard list; scholars still name a sign by its number, like *08, and write an unread sign that way.

Before you can study a script, you need a way to talk about its signs. In Arthur Evans at Knossos, 1900 you saw that Evans kept most of the tablets to himself. When the Pylos tablets were published in 1951, the American scholar Emmett L. Bennett Jr. sorted every Linear B sign into a numbered list. Scholars still use his numbers.

Key idea

Each Linear B sign has a number in a standard list, written with an asterisk: *08 is the sign read a, *01 is da, *70 is ko. A sign whose value is still unknown is written by its number alone, like *18.
A few signs with their numbers. The numbers are labels in a list; the values came later.

Why number the signs?

Sorting signs is harder than it sounds. Two scribes may draw the same sign quite differently, and two different signs may look alike. Bennett compared thousands of examples to decide which shapes were variants of one sign and which were separate signs. Then he gave each a number. Now two scholars on different continents could write "*70" and mean exactly the same sign, with no guessing about its sound.

ko-no-so (Knossos) with each sign numbered and its Bennett number in the breakdown. Tap a sign.

Why it works

Why did a neutral number matter so much? Because any name that hints at a sound biases the reader. If you call a sign "the ka sign" before you know its value, you start seeing ka everywhere. A number is a label with no meaning, so it lets you count, compare and sort signs fairly. Alice Kober and Michael Ventris both worked with signs as numbered shapes before any sound was known.

Common mistake

Treating a sign number as a sound. *08 does not mean "eight" or any sound; it is only the sign's place in the list. Its value, a, was found later, by the decipherment. Check: you can say "*08 is a", but never "*08 sounds like 8".

Numbers today

The numbering was adopted by scholars as the standard in the 1960s and is still used, with additions. When you read a transliteration such as *18-to, the asterisk number tells you the scribe wrote a sign whose value is not agreed (Signs Still Unread). Logograms have numbers too: the man sign is *100, the horse *105, the tripod *201.

Worked example: Number to value

The sign *08 begins the word a-mi-ni-so. What is its value?
  1. *08 is the sign for the vowel a.
  2. a-mi-ni-so begins with that sign.

Answer: a

Worked example: How to write it

A word has a sign whose value nobody knows, Bennett number 47, followed by da. How do scholars write it?
  1. An unread sign is written by its number with an asterisk.
  2. Signs are joined by hyphens.

Answer: *47-da
