Лев Диакон
According to the contemporary historian Leo the Deacon, during his triumphal procession Tzimiskes rode on a white horse behind a wagon carrying an icon of the Virgin Mary as well as the Bulgarian regalia, with the captive Boris II of Bulgaria and his family following behind Tzimiskes. The later account of John Skylitzes differs in some details in the description of the procession, but both sources agree that on this occasion, Tzimiskes rode a white horse, and that two Bulgarian crowns played an important role in the proceedings. Both authors also agree that one of these crowns was a "tiara" (i.e. the "toupha"), in accordance with the ""’s depiction.
