[6] Sísar ‘Sísarr’: Name for the ruler of Kiev (ON Kænugarðr), according to the prose text. The name itself is probably derived from Lat. Caesar (cf. Gautr 1900, ic) and perhaps reflects a generalised awareness of the princely status ascribed to the rulers of Kiev in the late Viking Age and later (cf. Melnikova 1996 for a discussion of such legends).
