Theogony and Works and Days are said to have been written by Hesiod (8th – 7th century BC) . Theogony describes the origins of the Greek gods, how they came to be and how they established permanent control over the cosmos. It is the first known Greek mythical cosmogony.
Works and Days is a farmer’s almanac in which Hesiod instructs his brother in the agricultural arts. In the same poem, Hesiod also offers his brother extensive advice on how to live his life. Works and Days revolves around two general truths: labour is the universal lot of Man, but he who is willing to work will get by. This poem is one of the earliest known musings on economic thought.
