heraclius and tong yabghu (called ziebel in the byzantine sources) met under the walls of narikala. the yabgu rode up to the emperor, kissed his shoulder and made a bow. in return, heraclius hugged the barbarian ruler, called him his son, and crowned him with his own diadem. during the ensuing feast the khazar leaders received ample gifts in the shape of earrings and clothes, while the yabghu was promised the hand of the emperor's daughter, eudoxia epiphania.
