Dinarchus

Dinarchus or Dinarch (Greek: Δείναρχος; Corinth, c. 361 – c. 291 BCE) was a logographer (speech writer) in Ancient Greece. He was the last of the ten Attic orators included in the "Alexandrian Canon" compiled by Aristophanes of Byzantium and Aristarchus of Samothrace in the third century BCE.

A son of Sostratus (or, according to the Suda, Socrates), Dinarchus settled at Athens early in life, and when not more than twenty-five was already active as a logographer—a writer of speeches for the law courts. As a metic, he was unable to take part in the debates. He had been the pupil both of Theophrastus and of Demetrius Phalereus, and had early acquired a certain fluency and versatility of style.

In 324 the Areopagus, after inquiry, reported that nine men had taken bribes from Harpalus, the fugitive treasurer of Alexander. Ten public prosecutors were appointed. Dinarchus wrote, for one or more of these prosecutors, the three speeches which are still extant: Against Demosthenes, Against Aristogeiton, and Against Philocles.
