1.1.1. Asymmetrical syllabic signs

The characteristic of the asymmetrical syllabic signs is it they can be written using 8 different dispositions on the writing surface to denote syllables using one consonant with 8 vowels in a monosemic (unambiguous) way.

We identified 13 asymmetrical signs in the analyzed text. They are the following:

as the signs for 13 consonants.

As mentioned above, each of these 13 signs in the writing surface, can be written in using 8 dispositions, as follows:

In this way, with only 13 different asymmetrical signs 13x8=104 syllables of the consonant-vowel type can be written in an unambiguous way.

The asymmetrical signs noted under the numbers 1, 3, 5, 7, 8 and 9, in the positions written under the numbers 1, 3, 5 and 7 were used in the 16th century as signs for writing numbers by the well-known mathematician Cardan, in his work Systems for Writing Numbers.

As in the analyzed text, where the consonant was determined by the form of the sign, and the vowel in the syllable was determined by the position of the sign, in his work Cardan determined the numbers with the form of the sign, and determined weights with their disposition (ones, tens, hundreds and thousands) in the number, as shown below.

If we recall that the Rosetta text dates from the second century B.C. and was written on the territory of Egypt, while Cardan was working in the 16th century A.D. in Italy, we can conclude that after 1800 years there was still a knowledge in the Mediterranean area about the signs in the Rosetta text.
