Slaves are a regular feature of Greek tragedy, even in minor roles
There is little reflection on the morality of slavery, but their presentation gives insight into the values of the audience
Tragedy slaves tended to be loyal to their masters, and there is no suggestion that they might resent their position
The 2nd Messenger in Bacchae says that he feels sorrow for the Theban royal house, even though he is only a slave (1027-8; 883-5)
Tragedy does reveal some of the hardships of a slave’s life
Oedipus threatens to torture the shepherd when he refuses to answer his questions (1152=4; 1266-9)
While Oedipus behaves harshly, the speed in which he resorts to violence is more shocking to the modern audience – ancients see slaves as their property
We see the humiliation of slavery when Oedipus assumes Jocasta’s distress at learning the story of his birth is because she thinks he was the child of a slave (1062-85; 1164-94)
To Oedipus, it is unsurprising that Jocasta should be horrified at the idea of being married to someone of slavish descent, and therefore he brushes off her pleas
