Prometheus Bound is an Ancient Greek tragedy. In Antiquity, this drama was attributed to Aeschylus, but is now considered by some scholars to be the work of another hand, perhaps one as late as ca. 415 BC. Despite these doubts of authorship, the play's designation as Aeschylean has remained conventional. The tragedy is based on the myth of Prometheus, a Titan who was punished by the god Zeus for giving fire to mankind.
The play is composed almost entirely of speeches and contains little action since its protagonist is chained and immobile throughout. At the beginning, Kratos (Force), Bia (Violence), and Hephaestus the smith-god chain Prometheus to a mountain in the Caucasus and then depart. According to the author, Prometheus is being punished not only for stealing fire, but also for thwarting Zeus' plan to obliterate the human race. This punishment is especially galling since Prometheus was instrumental in Zeus' victory in the Titanomachy. - Wikipedia
