The northeastern Iberian script, also known as Levantine Iberian or simply Iberian, was the primary means of written expression for the Iberian language. It has also been used to write Proto-Basque, as evidenced by the Hand of Irulegi.[1] The Iberian language is also represented by the southeastern Iberian script and the Greco-Iberian alphabet. In understanding the relationship between the northeastern and southeastern Iberian scripts, some note that they are two distinct scripts with different values assigned to the same signs. However, they share a common origin, and the most widely accepted hypothesis is that the northeastern Iberian script was derived from the southeastern Iberian script. Some researchers have concluded that it is linked solely to the Phoenician alphabet, while others believe that the Greek alphabet also played a role.
All the Paleohispanic scripts, with the exception of the Greco-Iberian alphabet, share a common distinctive typological characteristic: they represent syllabic values for the occlusives and monophonemic values for the other consonants and vowels. In this writing system, they are neither alphabets nor syllabaries; rather, they are mixed scripts that are typically identified as semi-syllabaries. The basic signary (non-dual) contains 28 signs: 5 vowels, 15 syllabic signs, and 8 consonantal signs (including one lateral, two sibilants, two rhotics, and three nasals).
The northeastern script was nearly deciphered in 1922 by Manuel Gómez-Moreno Martínez, who systematically linked the syllabic signs to their occlusive values. This decipherment was based on the existence of a large number of coin legends (some bearing Latin inscriptions) that could easily be associated with ancient place names known from Roman and Greek sources.
There are two variants of the northeastern Iberian script: the dual variant, which is almost exclusive to ancient inscriptions from the 4th and 3rd centuries BCE, is characterized by the use of a dual system. This system, discovered by Joan Maluquer de Motes in 1968, allows for the differentiation of occlusive signs (dentals and velars) between voiced and unvoiced by the addition of an extra stroke. The simple sign represents the voiced value, while the complex sign represents the unvoiced value. The non-dual variant is primarily found in modern inscriptions from the 2nd and 1st centuries BCE.
The inscriptions that use the northeastern Iberian script have been found primarily in the northeastern quadrant of the Iberian Peninsula, largely along the coast from Roussillon to Alicante, as well as deep into the Ebro Valley. These inscriptions have been discovered on various types of objects, including silver and bronze coins, silver and ceramic vessels, lead plaques, mosaics, amphorae, stones (steles), spindle whorls, and more. Together, these represent 95% of the total finds (over 2,000 items), and nearly all the scripts were written from left to right. The oldest northeastern Iberian inscriptions date to the 4th or possibly the 5th century BCE, while the more modern ones date from the end of the 1st century BCE or perhaps the beginning of the 1st century CE.
In recent years, four northeastern Iberian abecedaries or signaries have been published: the Castellet de Bernabé signary, the Tos Pelat signary, the Ger signary, and the Bolvir signary, all of which belong to the dual variant of the script.
