ABSTRACT
This chapter presents the complete edition of the texts X, Y and Z, which were only partially published, while the complete copies of W and A' are still missing. The data currently available consequently show that this writing system was used at least between 2500—2400 and 1900—1800 BC in southern Iran. The hypothesis of a genetic link between Proto-Elamite writing, which disappeared around 2800 BC, and LE writing is furthermore far from being proven. The Puzur-Insusinak LE inscriptions still remain best track towards the decipherment of the writing system. While the urban occupation completely collapsed in south-eastern Iran in the beginning of the 2nd millennium BC, the cuneiform writing system probably played an important role at that time in the abandonment of the LE system in south-western Iran. Created several centuries after the disappearance of the Proto-Elamite tablets, LE writing was until considered as a phenomenon mainly restricted to Susa in general and Puzur-Insusinak's epoch in particular.
