Anatolius the Bishop

Anatolius of Alexandria, bishop of Laodicea in Syria, who flourished in the reign of the emperors Probus and Carus, was a man of wonderful learning in arithmetic, geometry, astronomy, grammar, rhetoric and dialectic. We can get an idea of the greatness of his genius from the volume he wrote On the Passover and from his ten books On the Principles of Arithmetic. [a]
