Deioces,Diako, Deyaco, Diyako or Deiokes (Greek ???????) was the first king of the Medes according to Herodotus. In the late 8th century BC there was a Daiukku or Dayukku[1] who was a Mannaean provincial governor. Perhaps Herodotus uses the name in error.[
Deioces in Herodotus
Herodotus (I: 96ff) says that Deioces (Deyaco), father of Phraortes, was "a man of great ability and ambitious for power" in a time when there was no government in the region; people in his own and other villages chose him to arbitrate disputes, and eventually selected him as their king: "Let us appoint one of our number to rule us so that we can get on with our work under orderly government, and not lose our homes altogether in the present chaos."[3] They built him first a palace and then a capital, Ecbatana (modern Hamadan). He established a strict protocol of seclusion and deference as well as a nationwide network of spies, administered justice, and ruled for fifty-three years; his son and successor was Phraortes, father of Cyaxares, who overthrew the Assyrian Empire and established the power of Media.
Rüdiger Schmitt writes:
Herodotus account seems to have been based on an oral tradition; from it scholars have deduced that Deioces was the founder of the Median royal dynasty and the first Median king to gain independence from Assyria. But it must be stressed that Herodotus report is a mixture of Greek and eastern legends and is not historically reliable. It has also been supposed ... that the Median king on whom Herodotus account is centered was actually Deioces son Phraortes, and it is therefore impossible to give the exact dates of Deioces reign, which probably spanned most of the first half of the 7th century B.C.E.[4]
Daiukku in Assyrian inscriptions
A Daiukku is mentioned several times in inscriptions from the reign of Sargon II (late eighth century BC); he is named as a Mannean provincial governor (aknu) ruling a district bordering Assyria. His son was held hostage by the Urartians, and he supported the Urartian king against the Mannean ruler Ullusunu, but Sargon captured Daiukku and exiled him and his family to Hamath in Syria. "Any connection between the governor mentioned by Sargon and the Median dynasty of later periods is thus only hypothetical; there is not a single authentic cuneiform source to confirm that Sargons Daiukku and Herodotus Deioces were the same person."[5]
