Demetrius was born in
Phalerum, c. 350 BC. He was the son of Phanostratus, a man without rank or property, and was brother to the anti-Macedonian orator
Himeraeus. He was educated, together with the poet
Menander, in the school of
Theophrastus. He began his public career about 325 BC, at the time of the disputes concerning
Harpalus, and soon acquired a great reputation by the talent he displayed in public speaking. He belonged to the pro-oligarchic party of
Phocion, and he acted in the spirit of that statesman. When
Xenocrates was unable to pay the new
tax on
metics (foreign residents) c. 322 BC, and the Athenians threatened him with slavery, he was only saved (according to one story) when Demetrius purchased his debt and paid his tax. After the death of Phocion in 317 BC,
Cassander placed Demetrius at the head of the administration of
Athens. He filled this office for ten years, instituting extensive legal reforms. One famous innovation implemented by Demetrius was the restriction of funerary luxury via a
sumptuary law, which is not only known from a mention in Cicero, but is also clearly visible in the archaeologically documented cemeteries of Athens. The Athenians conferred upon him the most extraordinary distinctions (almost all of which were revoked after his later expulsion from Athens), and no fewer than 360
statues were erected to him. However, Demetrius was unpopular with the lower classes of Athenians and with pro-democratic political factions, who resented the limitations he placed on the democratic franchise and viewed him as little more than a pro-Macedonian puppet ruler. According to
Stephen V. Tracy, the story about the statues was not historical; also he argues that Demetrius later played a big role in the foundation of the
Library of Alexandria. He remained in power until 307 BC when Cassander's enemy,
Demetrius Poliorcetes, captured Athens, and Demetrius was obliged to take to flight. It was claimed that during the latter period of his administration he had abandoned himself to every kind of excess, and we are told he squandered 1200 talents a year on dinners, parties, and love affairs.
Carystius of Pergamum mentions that he had a lover by the name of Theognis, of whom all the Athenian boys were jealous. After his exile, his enemies contrived to induce the people of Athens to pass the
death sentence upon him, in consequence of which his friend Menander nearly fell victim. All his statues, with the exception of one, were demolished. Demetrius first went to
Thebes, and then (after Cassander's death in 297 BC) to the court of
Ptolemy I Soter at
Alexandria, with whom he lived for many years on the best terms, and who is even said to have entrusted to him the revision of the laws of his kingdom. During his stay at Alexandria, he devoted himself mainly to literary pursuits, ever cherishing the recollection of his own country. On the accession of
Ptolemy Philadelphus, Demetrius fell into disfavour (he apparently supported the wrong candidate,
Ptolemy Keraunos), and was sent into exile to
Upper Egypt. According to one account, a statue at Memphis
Saqqara was attributed to him. He is said to have died from
the bite of a
venomous snake and was buried in
Diospolis Kato. His death appears to have taken place soon after the year 283 BC. ==Works and legacy==
