The Wheel of God, by Sophocles

The Wheel of God

In many a turning of the wheel of God
My fate revolves and changes all its mood;
E'en as the moon's face never keepeth still
For but two nights in one position fixed,
But from its hiding-place first comes as new,
With brightening face, and thenceforth waxeth full;
And when it gains its noblest phase of all,
Wanes off again, and comes to nothingness.
