Aeschylus

Wisdom comes through suffering. Trouble, with one’s luck turned, teaches a student.

Myriad laughter of the ocean waves.

For the poison of tyranny is the endless fear of retribution.

Happiness is a choice that requires effort at times.

The man who runs may fight again.

Only when man's life comes to its end in prosperity can one call that man happy.

Bronze is the hardest metal, but iron cuts it.

Let us be of good cheer, however, remembering that the misfortunes of others do not necessarily bring happiness to ourselves.

The seed of justice grows in the soil of injustice.

Words are the physicians of a mind diseased.

There is no sickness worse than a diseased mind.

The unnamable has no name.

What is pleasanter than the tie of host and guest?

Ares, the bloody scourge of mortal men.

Justice, do not let the law be trampled underfoot.

The mind of the wise man is like a garden of flowers.

Suffering is the teacher of wisdom.

The gods visit the sins of the fathers upon the children.

Hope is the only good that is common to all men; those who have nothing else possess hope still.

Excessive prosperity brings great evils.
