Euripides

A bad beginning makes a bad ending.

Chance fights ever on the side of the prudent.

Judge a tree from its fruit; not from the leaves.

Talk sense to a fool and he calls you foolish.

The good and the wise lead quiet lives.

Time will explain it all. He is a talker, and needs no questioning before he speaks.

Waste not fresh tears over old griefs.

Who dares not speak his free thoughts is a slave.
- All from Euripides, 484 - 406 BC
