Perses is a loser who squandered his wealth and then sued for the poet's. Instead of money, Hesiod gives a poem instructing his brother in his farming methods and his theological concept of justice.
Works and Days wasn't meant to entertain, but to get Perses off his lazy ass and teach him to work for a living. Rather than wars or hero's journies, it shows us the daily life and thoughts of an ancient Greek citizen. Always flowing and never wasting words, Hesiod's masterwork of myths, metaphors, and minutiae is a superb read to this day.
