Then thou, when friends are far, shalt know

Stroke for stroke, and blow for blow.

Clytemnestra.

Hear thou this oath, that seals my cause with right:

By sacred Justice, perfecting revenge,

By Até, and the Erinnys of my child,

To whom I slew this man, I shall not tread

The threshold of pale Fear, the while doth live

Ægisthus, now, as he hath been, my friend,

Stirring the flame that blazes on my hearth,
