" The best surviving key to Rus greatness is Kiev’s Santa Sofia Cathedral, built in 1037 by one of the greatest Riurik princes, Prince Yaroslav the Wise. From the outside it looks much like any other baroque Ukrainian church, its original shallow Greek domes and brick walls long covered in gilt and plaster. But inside it breathes the splendid austerity of Byzantium. "
