25. CONSTANTINI PORPHYROGENITI PAEDAGOGUS. Theodore, tutor to the emperor Constantine Porphyrogenitus [CONSTANTINUS VII.] enjoyed during the minority of that accomplished but weak prince, considerable influence in the palace. The attempt of Leo Phocas and his brother-in-law, the chamberlain Constantine, to depose the young emperor, and confer the purple on Leo, were defeated by the vigilance of Theodore, who prevailed on the emperor to summon to his assistance Romanus, afterwards colleague of Constantine in the empire; who, probably, from finding Theodore's fidelity an obstacle to his advancement, caused him and his brother Simeon to be banished from Constantinople to their estates in the Opsician thema, on the Asiatic side of the Bosporus.
