There are four distinct species of Tragedy—that being the number of the constituents also that have been mentioned: first, the complex Tragedy, which is all Peripety and Discovery; second, the Tragedy of suffering, e.g. the Ajaxes and Ixions; third, the Tragedy of character, e.g. The Phthiotides and Peleus. The fourth constituent is that of 'Spectacle', exemplified in The Phorcides, in Prometheus, and in all plays with the scene laid in the nether world.
