(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.)
