Dēmētrius
1. Demetrius of Phalērum (c.350–c.283 BC), Athenian statesman and philosopher. He was pro-Macedonian and favoured Cassander's cause. When most of the Greek states including Athens surrendered to Cassander in 318, the latter made Demetrius governor of Athens, where he ruled in an enlightened manner for ten years. He went into exile when the Macedonian Demetrius Poliorcetes took Athens in 307, and later joined the Egyptian court of Ptolemy I Soter at Alexandria. He had studied at the Peripatetic school of philosophy in Athens as the pupil of Theophrastus, and it is probable that he advised Soter about the foundation of the Alexandrian Library and possibly about the Museum too. He is thus partly responsible for their being organized in the Peripatetic fashion and spirit, which accounts for the nature and trend of much of the intellectual life of Alexandria. After Ptolemy II Philadelphus became sole ruler in 283 BC Demetrius was exiled to Upper Egypt where he died. He was an outstanding orator and the author of many scholarly works of which only fragments survive.
2. Demetrius Poliorcētēs, Macedonian general, famous for his unsuccessful siege of Rhodes in 305–304 BC, commemorated by the Colossus of Rhodes.
3. Greek author of a treatise ‘On Style’ (Peri hermeneiās), traditionally said to be Demetrius of Phalerum (see above), but the style and contents suggest a date at least a century later, and the work perhaps belongs to the first century BC. The author analyses style (charactēr) under four headings (rather than the more usual three; compare ORATOR): plain (ischnos), grand (megaloprepēs), elegant (glaphyros), and forceful (deinos); the last category is a novelty in this kind of criticism. He also gives an account of style in letter-writing, a literary genre usually ignored by other ancient critics.
