This play combines a piece of the story of “The Iliad” with a love story that wasn’t part of the Iliad, but which is based on minor characters from the Iliad. [For those unacquainted, “The Iliad” tells the tale of the siege of Troy after a prince from Troy, Paris, returns home with Helen, the wife of the Spartan king Menelaus, and the Greeks launch “a thousand ships” to try to get her back.] Even the romance isn’t original to Shakespeare as the Troilus and Cressida tale had already been told and retold, and Shakespeare’s telling is said to have been influenced by Chaucer’s.
While most of Shakespeare’s plays are readily categorized as comedy or tragedy, this is one of the few that defies such characterization. In terms of how the story resolves itself, one might call it a tragedy, but the tone throughout is often more comedic.
The part of the Iliad that is told is largely about the Greek generals trying to get Achilles back in the fight because he is the best match for Hector, the mightiest of the Trojan princes. The love story pivots on Cressida being given to the Greeks as part of a prisoner exchange, and – as is often the case – features a heaping dose of jealousy that sours this great love affair.
This is definitely a worthwhile read, despite criticism that it feels muddled. One doesn’t need to have read the Iliad, though it may help to make it more entertaining.
