Artystone

Artystone (; ; Elamite , ) also known as Irtašduna in the Fortification tablets, was a Persian princess, daughter of king Cyrus the Great, and sister or half-sister of Cambyses II, Atossa and Smerdis (Bardiyā). Along with Atossa and her niece Parmys, Artystone married king Darius I. It is argued that by marrying the female offspring of Cyrus, the founder of the empire, the new king aimed to prevent his rule from being contested, since Darius himself was not of royal blood.
