What is a king?

Chorus: You are the state, you are the people.
Rule unquestioned, you control
The altar that is your country’s hearth;
You fear no vote; by your mere nod
You, monarch on one throne, decide all issues:
Therefore, guard against guilt.

Aeschylus’ The Suppliants. Chorus of the Danaids addressing King Pelasgus, ruler of Argos.
