The southeastern Iberian script, also known as Meridional Iberian, was one of the means of written expression of the Iberian language, which was written mainly in the northeastern Iberian script and residually by the Greco-Iberian alphabet. About the relation between northeastern Iberian and southeastern Iberian scripts, it is necessary to point out that they are two different scripts with different values for the same signs; however it is clear that they had a common origin and the most accepted hypothesis is that northeastern Iberian script derives from southeastern Iberian script. In fact, the southeastern Iberian script is very similar, both considering the shape of the signs or their values, to the Southwestern script used to represent an unknown language usually named Tartessian. The main difference is that southeastern Iberian script doesn’t show the vocalic redundancy of the syllabic signs. Unlike the northeastern Iberian script the decipherment of the southeastern Iberian script is not yet complete, because there are a significant number of signs on which scholars have not yet reached a consensus. Despite it is believed that unlike the northeastern Iberian script the southeastern Iberian script doesn’t show any system to differentiate between voiced and unvoiced occlusives, a recent paper (Ferrer i Jané 2010) defends the existence of a dual system also in the southeastern Iberian script.
