a Greek author and Platonic philosopher, who wrote Commentaries on Plato's Polities, which are lost; but his name is particularly famous for a treatise entitled Λόγος Ἐρευνητικός, "Of the duty and virtues of the general of an army?" which has been translated into Latin, Italian, Spanish, and French. The time when he lived is not precisely known: but is imagined to be in the reign of the emperor Claudius.
