"The coins of Kujula and his immediate successors give the king’s name and titulature in Greek, often with a Kharoṣṭhī version on the reverse. The earliest issues of Kanishka likewise bear on the obverse his name and title in Greek (basileus basileōn kanēškou “[coin] of Kanishka, king of kings”), while the reverses portray divinities named in Greek as Hēphaistos, Hēlios, Nanaia, and Selēnē. Later issues follow the same pattern, but the legends are henceforward in Bactrian rather than Greek. Kanishka’s titulature appears (in its fullest form) as šaonano šao kanēški košano “of Kanishka, king of kings, the Kushan,” that of his successor Huvishka as šaonano šao ooēški košano. The forms kanēški and ooēški (also ouoēški, ooēške) are in the oblique case, cf. the Greek gen. kanēškou; a few coins of Huvishka have the nom. form (ooēško), as do those of the succeeding rulers, (bazodēo), Kanishka II (kanēško), Vasishka (bazēško, cf. R. Göbl, Dokumente zur Geschichte der iranischen Hunnen in Baktrien und Indien, Wiesbaden, 1967, III, pl. 8), etc.
Surkh Kotal (Persian: سرخکوتل), also called Chashma-i Shir or Sar-i Chashma, is an ancient archaeological site located in the southern part of the region of Bactria, about 18 km north of the city of Puli Khumri, the capital of Baghlan Province of Afghanistan.....It is the location of monumental constructions made during the rule of the Kushans. Huge temples, statues of Kushan rulers and the Surkh Kotal inscription, which revealed part of the chronology (another fragment of that chronology was found on the Rabatak inscription found nearby) of early Kushan emperors (also called Great Kushans) were all found there.... The most famous artifacts of this site are the Surkh Kotal inscriptions, the statue of King Kanishka and the fire altar.".....http://en.wikipedia.org/wiki/Surkh_Kotal

"The Rabatak inscription is an inscription written on a rock in the Bactrian language and the Greek script, which was found in 1993 at the site of Rabatak, near Surkh Kotal in Afghanistan. The inscription relates to the rule of the Kushan emperor Kanishka, and gives remarkable clues on the genealogy of the Kushan dynasty."
"The Rabatak inscription.....(Translation by Nicholas Sims-Williams)  . . . of the great salvation, Kanishka the Kushan, the righteous, the just, the autocrat, the god  worthy of worship, who has obtained the kingship from Nana and from all the gods, who has inaugurated the year one  as the gods pleased.
