Arukku
Arukku ( Assyrian A-ru-uk-ku, Old Persian Harriukqa / Hariuwuka, Iranian Aryavuka / Aryuka, Aramaic Aryuk ; * before 656 BC..) was the eldest son of King Kuras ( Cyrus I) from Parsumaš .
In connection with the destruction of Susa, effectively the dissolution of the kingdom of Elam by Ashurbanipal, Kuras (Cyrus I) sent his son Arukku to Nineveh to recognize the supremacy of the Assyrians in 639 BC. The distinction equating Parsua with Parsumaš would mean that the here referenced Cyrus might have meanwhile taken over the sovereignty of one of many kings. In 835 BC, in the 24th year of the reign of Shalmaneser III, Parsua was described as a country with 27 kings.
