A look at prince Svyatoslav's family, XI centuary

In the book of N. Kaminskaya "The history of a costume (suit)" I have red about the Russian costumes of X-XIV centuries. In the book I have found this drawing. It is from the handwritten book "Izbornik of Svyatoslav" which had been written at 1073 for Svyatoslav, a prince of Kiev. At the drawing there is prince Svyatoslav and his family.

The prince is wearing green caftan (also named svita), blue cloak corzno, round hat with the fur and green boots made from morocco (a kind of leather).
