Specifically, however, Stevenson consciously borrowed material from previous authors. In a July 1884 letter to Sidney Colvin, he writes "'Treasure Island' came out of Kingsley's 'At Last,' where I got the Dead Man 's Chest - and that was the seed - and out of the great Captain Johnson's 'History of the Notorious Pirates.'" Stevenson also admits that he took the idea of Captain Flint's skeleton point from Poe's "The Gold-Bug," and he constructed Billy Bones ' history from the pages of Washington Irving, one of his favorite writers.
The tyranny under which Argos finds itself at the end of Agamemnon corresponds in a very broad way some events in the biographical career of Aeschylus. During his life, Aeschylus is know to have made at least two visits to the court of the Sicilian tyrant Hieron. It was a place that lured some of the other great poets of his day, Simonides, Pindar, and Bacchylides. He was also alive to see the democratization of Athens. The tension between, tyranny and democracy, is introduced in Agamemnon and, again, is developed more in the next two plays.
