A Dictionary of Greek and Roman biography and mythology

(Πραξαγόρας), an Athenian, lived after the time of Constantine the Great, probably under his sons. He wrote at the age of nineteen, two books on the Athenian kings; at the age of twenty-two, two books on the history of Constantine; and at the age of thirty-one, six books on the history of Alexander the Great. All these works were written in the Ionic dialect. None of them has come down to us with the exception of a few extracts made by Photius, from the history of Constantine. In this work Praxagoras, though a heathen, placed Constantine before all other emperors. (Phot. Bibl. 62.)
