A Stoic philosopher, Egyptian priest, and writer of the first century A.D. The exact dates of his life are not known, but he was active in a literary way from about A.D. 30 to A.D. 65. Only fragments of his works on the hieroglyphs, Egyptian history, and the comets have survived in later authors (collected and by van der Horst). According to the Suda, he was head of the school of grammarians in and perhaps curator of the famous museum before he went to Rome as tutor of the future emperor Nero.

His book on the hieroglyphs influenced later authors from OF and HORAPOLLON down to John Tsetzes in the twelfth century. His works betray a syncretistic mixture of Egyptian religious ideas and Stoic philosophy as well as magical and astrological conceptions.
