(Saints) Martyrs (July 24) (11th century) Two Princes, sons of Vladimir, the first Christian Duke of Muscovy (Russia). Their zeal for the propagation of the Christian Faith led to their martyrdom at the hands of their heathen fellow-countrymen (A.D. 1010). Saint Romanus is known in the East as Saint Boris, a name very frequently given in Baptism, and Saint David as Gleb.
