Girl on an Altar

Higher & Ordinary Level · 2027 & 2028 Leaving Cert

Marina Carr’s Girl on an Altar takes the oldest story in Greek tragedy, a father who kills his daughter for a favourable wind, and asks what the marriage looked like for the ten years afterwards.

Carr wrote the play for the Kiln Theatre in London, where it opened in 2022. The source is the House of Atreus, the same material Aeschylus used in the Oresteia, but Carr’s method is different. Much of the play is spoken directly to us in narrated monologue, with characters describing their own actions in the present tense before stepping into the scene. The effect is that we hear people explain themselves and then watch them do the opposite.

It is prescribed for 2027 and 2028. Its great advantage as a study text is that the central conflict never resolves into a simple verdict, which is exactly what the higher grades reward.

Girl on an Altar: The Story in Five Beats

One. The Greek fleet is becalmed at Aulis. Agamemnon has been told the wind will not change until he sacrifices his eldest daughter. Iphigenia is brought there under a false story, that she is to marry Achilles. Clytemnestra travels with her, believing it.

Two. The truth arrives too late. Clytemnestra learns from her servant Cilissa what is happening on the altar and cannot stop it. She curses Agamemnon and everything he will touch.

Three. Ten years pass. Agamemnon is at Troy. Clytemnestra rules Mycenae, takes Aegisthus into her bed, and is never allowed to grieve openly for a daughter the state has decided did not really die.

Four. Agamemnon comes home with Cassandra, a Trojan princess taken as a prize, who is pregnant. He expects the marriage to resume. What follows is a long, strange stretch of the play in which the couple circle each other, argue, remember, and at moments come genuinely close to reconciling.

Five. Clytemnestra kills him, and Cassandra with him. The final movement gives the killing to us through several voices at once, and Cassandra narrates her own death.

A Marriage That Cannot Bury Its Dead

The engine of the play is not the murder. It is the ten years of not saying the girl’s name. Agamemnon’s method is erasure, and he is explicit about it: the household is instructed to behave as though Iphigenia never existed.

“Okay. I killed her.”Agamemnon, Act Two, Scene Four

That admission arrives very late, and it is grudging. Before it he offers Clytemnestra every substitute he can think of, another daughter, another life, and the offers are worse than the silence, because each one shows he thinks a child is replaceable.

Two Sets of Tied Hands

Agamemnon’s defence throughout is that he had no choice: the army would have deposed him, the men were close to mutiny, and the decision was political rather than personal. Carr gives him the argument in full and then hands Clytemnestra one line that dismantles it.

“My hands were tied.”Agamemnon, Act Two, Scene Two

“Iphigenia’s hands were tied.”Clytemnestra, Act Two, Scene Two

Four words against four words. He means it as a figure of speech. She returns it as a fact about a body on an altar. If you take one exchange out of this play for an exam answer, take this one, because it does the whole argument in a breath.

What Can Be Done to a Girl

Carr keeps widening the frame from one killing to a pattern. Cassandra is a prize of war and pregnant by the man who took her city. Cilissa is a servant with no standing. Clytemnestra herself is a queen who is still told that politics is not her business.

“But a girl. You can do anything to a girl.”Clytemnestra, Act Two, Scene Four

Notice how flat that line is. No rhetoric, no curse. It is presented as an observation about how the world is arranged, and the play spends two acts proving it.

Violence That Runs in the Family

The House of Atreus is a chain of these crimes and everyone in the play knows the history. Aegisthus was born into it: his brothers were killed by Agamemnon’s father and served at a table. Agamemnon watched his own father kill his mother when he was nine. Carr uses this to complicate blame without excusing anybody.

“You’re no king. You’re a tainted cut throat, a daughter slayer.”Clytemnestra, Act Two, Scene Two

Tyndareus, Clytemnestra’s father, is the outside voice. He arrives to say the obvious thing, that this is the bronze age and civilised people do not put children on altars to change the weather, and his outrage lands because he is the only character with no blood on him.

Who’s Who

Clytemnestra is the play’s centre. Grieving, furious, politically capable and, in the long middle section, disturbingly still in love with the man who did it. Carr refuses to make her either a victim or a monster.

Agamemnon is charming in company, brutal in private, and sincerely puzzled that his wife has not moved on. His self-pity is the most uncomfortable thing in the play.

Cassandra narrates her own captivity and her own death. She is the closest thing to a neutral witness, and she sees the household clearly because she is outside it.

Cilissa is the servant who watches the sacrifice and has to describe it. She also delivers one of the play’s coldest observations about freedom, that being wished free by somebody else is not the same as being free.

Aegisthus and Tyndareus supply the two views of the family curse, one from inside it and one from outside.

Using This in the Exam

How to use it: Anchor answers to three moments: the sacrifice reported by Cilissa in Act One, the tied-hands exchange in Act Two, and the killing narrated in the final scene. Between them they cover power, gender, grief and revenge, so you can meet most questions without new material. Carr’s narrated monologue is worth a sentence in any answer about how the play is told, because a character describing their own actions in the present tense is a very different thing from a character simply doing them.
