Arsames
Arsames (Old Persian: Aršâma): grandfather of the Persian king Darius I. A short inscription by Arsames, known as AsH, was found on a golden tablet in Hamadan (ancient Ecbatana) and runs like this:
Arsames, the great king, king of kings, king in Persia, son of king Ariaramnes, an Achaemenian. King Arsames says: the great god Ahuramazda, greatest of gods, made me king. He bestowed on me the land Persia, with good people, with good horses. By the favor of Ahuramazda I hold this land. May Ahuramazda protect me, and my royal house, and may he protect this land which I hold.
It is unclear when this text was made. It can be a fraud (modern or ancient), but it may be an original document.
