Ancient Greek literature
Seven works of Sophocles have survived, the most acclaimed of which are the three Theban plays, which center around the story of Oedipus and his offspring. The Theban Trilogy consists of "Oedipus the King", "Oedipus at Colonus", and "Antigone". Although the plays are often called a "trilogy," they were actually written many years apart. "Antigone", the last of the three plays sequentially, was actually first to be written, having been composed in 441 BC, towards the beginning of Sophocles's career. "Oedipus the King", the most famous of the three, was written around 429 BC at the midpoint of Sophocles's career. "Oedipus at Colonus", the second of the three plays chronologically, was actually Sophocles's last play and was performed in 401 BC, after Sophocles's death.
Against Aristogeiton
The first speech was generally accepted as authentic by ancient authorities – Dionysius of Halicarnassus is the only ancient author to dispute that Demosthenes wrote it. Other ancient authors, including Pliny the Younger and the author of "On the Sublime", accept it as Demosthenic. Since the 19th century, however, the authorship has been questioned, primarily on the basis that it makes mistakes about Athenian law which Demosthenes would not have. Additionally, Raphael Sealey challenges the speech on the grounds that it contradicts other sources on Aristogeiton at a number of points. Sealey therefore concludes that the speech was a later rhetorical exercise. Friedrich Blass attributed the speech to Demosthenes, but considered it "repetitive, confused and disorderly" and therefore suggested that it was drafted, but never delivered, by him. More recently, Douglas MacDowell has argued that "Against Aristogeiton I" is correctly attributed to Demosthenes.
