Traditional Ostrogski coat of arms was described in his work
Kasper Niesiecki, while its iconographic representation is seen on the
Ostroh Bible. According to Niesiecki the first (oldest) Ostrogski coat of arms was
Pogoń Ruska coat of arms where the
Saint George pierces a dragon (see
Saint George and the Dragon). During the
Battle of Vedrosha on 14 July 1500 the Grand Hetman of Lithuania Konstanty Ostrogski was taken a prisoner by the Muscovite forces and later sent to
Vologda.
Nikolay Karamzin cites that on 18 October 1506 Ostrogski pledged his allegiance to the Grand Prince of Moscow
Vasili III as a
boyar, confirmed by the Metropolitan of Moscow
Simon. Ostrogski was sent then to the
Sloboda Ukraine to fight Tatars, but managed to escape and returned to Lithuania in 1507. After Konstanty Ostrogski returned from the Muscovite captivity he adopted a new coat of arms (his former coat of arms was to similar to that of the
Grand Duchy of Moscow). The new coat of arms was created as a mix of Leliwa and Ogończyk coat of arms, in remembrance of his two sons Eliasz (whose wife Beata Kościelecka was of
Ogończyk coat of arms) and
Konstanty (whose wife
Zofia Tarnowska was of
Leliwa coat of arms). According to the
Book of Knowledge of All Kingdoms, the coat of arms for country of Roxia (Ruthenia) was described as a green field with an octagonal star, while its banner consists of two golden half-moons at a silver field pointing with their horns at each other. To the similarity of the description points
Roman Klymkevych. ==Notable bearers==
