With the reign of Shutruk-Nahhunte begins one of the most glorious periods in Elamite history. During a space of almost seventy years five kings succeed to the throne: Shutruk-Nahhunte, Kutir-Nahhunte, Shilkhak-In-Shushinak, Khutelutush-In-Shushinak and Silkhinakhamru-Lakamar. Their personal qualities were to make Elam one of the greatest military powers in the Middle East for a period lasting over fifty years. Susa owes much of its splendour to Shilkhak-In-Shushinak. There are many texts which commemorate the foundation or restoration of temples at Susa. A curious bronze tray known as the sīt šamši, 'sunrise' shows us certain ablution rites, for it is probably a model of the acropolis of Susa, with two of its temples, their appurtenances, their ornaments and sacred grove, at the time of Shilkhak-In-Shushinak. This allows us to complete, to a certain extent, the information we have from the excavations concerning the topography of Susa. The chapter also presents a note on the political geography of Western Persia.
