which alone has preserved his memory and excused his ambition. A particle of the treasures of his nephew was sometimes diverted from the indulgence of vice and folly; a school was opened in the palace of Magnaura; and the presence of Bardas excited the emulation of the masters and students. At their head was the philosopher Leo, archbishop of Thessalonica: his profound skill in astronomy and the mathematics was admired by the strangers of the East; and this occult science was magnified by vulgar credulity, which modestly supposes that all knowledge superior to its own must be the effect of inspiration or magic.

Whilst he exercised the office of protospathaire or captain of the guards, Photius was sent ambassador to the caliph of Bagdad.
