In the left panel, a bloody smear spreads across the floor from under an open door, and the Fury has blood spurting from an orifice. In each of the left and right panels, the monstrous form of a Fury is suspended in a wire framed box in front of an open door. In the central panel, the mutilated body of the king, with the spine exposed, is raised on a box-like dais, with blocks of the floor and wall coloured blood red. Each panel depicts abstracted body parts in a space delineated by cream walls meeting beige floors. The triptych form echoes a Christian altarpiece, with the main "crucifixion" in the central panel flanked by two supporting figures. The violence of The Oresteia found echoes in Bacon's own tortured personal life, from the physical abuse he suffered at the hands of his father, through his preference for roughly masochistic homosexual encounters, and the suicide of his lover George Dyer. In a letter sent to Michel Leiris in 1981, Bacon described re-reading read Aeschylus: he did not want to create a historical painting of one of the characters, such as Agamemnon or Clytemnestra rather, he tried "to create images of the sensations that some of the episodes created inside me … an image of the effect that was produced inside me." The Oresteia recounts three linked mythic tales of revenge: the first recounting the murder of King Agamemnon after he returned from the Siege of Troy, with Queen Clytemnestra killing her husband to avenge his sacrifice of their daughter Iphigenia to secure a safe journey home in the second, their son Orestes murders Clytemnestra to avenge his father and in the third, Orestes is pursued by the Erinyes, also known as the Furies, the three female deities of vengeance. The work draws inspiration from The Oresteia, a trilogy of ancient Greek tragic plays by Aeschylus, which was also an inspiration for other earlier large triptychs, including Bacon's 1944 breakthrough Three Studies for Figures at the Base of a Crucifixion.

It is one of 28 large triptych paintings by Bacon, each comprising three oil on canvas panels which measure 198 cm × 147.5 cm (78.0 in × 58.1 in). Triptych Inspired by the Oresteia of Aeschylus is a 1981 oil on canvas triptych painting by Francis Bacon. Francis Bacon, Triptych Inspired by the Oresteia of Aeschylus, 1981
