The two inscription panels of Ganjnameh, carved in stone in 20 lines on a granite rock above a creek, measure 2 × 3 m each.[1][2] Written in Old Persian, Neo-Babylonian and Neo-Elamite, except for the different royal name, the contents of the two inscriptions are identical; Ahura Mazda receives praise, and lineages and conquests are listed.[1][2] According to Stuart C. Brown, in the pre-Hellenistic period, this mountain was apparently the main "east-west pass" through Mount Alvand.[1] During the Achaemenid period, Ecbatana functioned as summer capital due to its high elevation and pleasant weather.[2]
The site received its name from local natives, who believed that the inscriptions contained the secret code to a hidden treasure.[2]
