One of Shakespeare's most notoriously difficult and cynical plays, labelled a "Problem Comedy", Troilus and Cressida has perplexed critics and theatre directors, and after Shakespeare's lifetime it was not performed again until 1907. In many ways the play's difficulty is a surprise; the story of Troilus and Cressida was a popular theme, drawn from Homer's Iliad and Chaucer's own Troilus and Criseyde, as was its classical setting, the Greek siege of Troy, led by Agamemnon, Achilles, Ajax, Diomedes and Ulysses.
