British classics scholar Edith Hall finds a possible thematic link between the three plays in the trilogy that included Alcmaeon in Corinth. Iphigenia in Aulis tells the story of King Agamemnon sacrificing his young daughter Iphigenia. The Bacchae tells the story of Agave killing her young adult son Pentheus. Similarly, Alcmaeon in Corinth incorporated the story of a parent's relationship with a youth.
