This slab is one of eight examples that were found together in a room in the Garrison Quarters, Persepolis. They were intended as foundation inscriptions, but were never used as such.

Five of the slabs are inscribed in Old Persian, two in Babylonian and one in Elamite. This example is in Old Persian. In the inscription Xerxes lists the countries of which he was king, and says that in one of them, false gods (daivas) were worshipped. He replaced them with the worship of Ahura Mazda and Arta
(‘order’, ‘truth’). The inscription reads:

Saith Xerxes the King: when that I became king, there is among these countries which are inscribed above [one which] was in commotion. Afterwards Ahura Mazda bore me aid; by the favour of Ahura Mazda I smote that country and put it down in its place.

And among these countries there was [a place] where previously false gods were worshipped. Afterwards, by the favour of Ahura Mazda, I destroyed that sanctuary of the demons, and I made proclamation, ‘The demons shall not be worshipped!’ Where previously the demons were worshipped, there I worshipped Ahura Mazda and Arta reverently.
