Naqsh-e Rustam is an ancient necropolis located about 12 km northwest of Persepolis, in Fars Province, Iran, with the best group of ancient rock reliefs in Iran cut into the cliff, from both the Achaemenid and Sassanid periods. It lies a few hundred meters from Naqsh-e Rajab, with a further group of Sassanid reliefs. The oldest relief at Naqsh-i Rustam dates to c. 1000 BC. Though it is severely damaged, it depicts a faint image of a man with unusual head-gear and is thought to be Elamite in origin. The depiction is part of a larger mural, most of which was removed at the command of Bahram II. The man with the unusual cap gives the site its name, Naqsh-e Rostam, “Rostam Inscription”, because the relief was locally believed to be a depiction of the mythical hero Rostam.
