Dinarchus

Dinarchus (c. 360 - c. 290 BCE) was the last of the canonical "Ten Attic Orators." Originally from Corinth, he settled in Athens as a resident foreigner and made his living writing speeches for others to deliver in court. His surviving speeches date from the famous corruption trials connected with the fugitive Macedonian treasurer Harpalus, and his style was regarded in antiquity as derivative of greater predecessors such as Demosthenes.
