Subtitle (titling) "Mario Kart" series; and "", the second in the "Star Trek" series. Subtitle (titling) In books and other works, a subtitle is an explanatory or alternate title. As an example, Mary Shelley gave her most famous novel the title "Frankenstein; or, the Modern Prometheus"; by using the subtitle "the Modern Prometheus", she references the Greek Titan as a hint of the novel's themes. In English, subtitles were traditionally denoted and separated from the title proper by the conjunction "or", perhaps hinting at their function as an alternate title. A more modern usage is to simply separate the subtitle by punctuation,
Prometheus Bound", perhaps the most famous treatment of the myth to be found among the Greek tragedies, is traditionally attributed to the 5th-century BCE Greek tragedian Aeschylus. At the center of the drama are the results of Prometheus' theft of fire and his current punishment by Zeus. The playwright's dependence on the Hesiodic source material is clear, though "Prometheus Bound" also includes a number of changes to the received tradition. Before his theft of fire, Prometheus played a decisive role in the Titanomachy, securing victory for Zeus and the other Olympians. Zeus's torture of Prometheus thus becomes a particularly harsh betrayal.
