This paper deals with the accounts of the “Great King of the Türks”, called Šâba, in the Iranian, Arabic and Transcaucasian sources, basing themselves on the Sâsânid “Book of Kings” (Ḫvadây Nâmag) and preserved in Iranian tradition. He is noted but unnamed in the Byzantine sources and appears, most probably, as Bağa Qağan/Chuluohou in the Chinese accounts. The Sâsânid hero Bahrâm Čôbîn defeated and killed him in a battle at Herat in 588. His name/title /honorific, like those of many of the early Türk rulers is not Turkic.
