Hesiod
Hesiod, the father of Greek didactic poetry, probably flourished during the 8th century BC. Hesiod's earliest poem, the famous Works and Days, and according to Boeotian testimony the only genuine one, embodies the experiences of his daily life and work, and, interwoven with episodes of fable, allegory, and personal history, forms a sort of Boeotian shepherd's calendar. The other poem attributed to Hesiod or his school which has come down in great part to modern times is The Theogony, a work of grander scope, inspired alike by older traditions and abundant local associations. It is an attempt to work into system, as none had essayed to do before, the floating legends of the gods and goddesses and their offspring.

“He's only harming himself who's bent upon harming another”
“But he who neither thinks for himself nor learns from others, is a failure as a man.”
“No gossip ever dies away entirely, if many people voice it: It too is a kind of divinity.”
“That man is best who sees the truth himself. Good too is he who listens to wise counsel. But who is neither wise himself nor willing to ponder wisdom is not worth a straw.”
“From their eyelids as they glanced dripped love.”
“…Perses, hear me out on justice, and take what I have to say to heart; cease thinking of violence. For the son of Kronos, Zeus, has ordained this law to men: that fishes and wild beasts and winged birds should devour one another, since there is no justice in them; but to mankind he gave justice which proves for the best.”
“A man who works evil against another works it really against himself, and bad advice is worst for the one who devised it”
“So you, the kings, you too must reflect upon this punishment, because the immortals are here in the midst of manking, observing those who do not hold the gods in awe...but grind each other down with crooked judgements”
