Hesiod's Theogony is a large-scale synthesis of a vast variety of local Greek traditions concerning the gods, organized as a narrative that tells how they came to be and how they established permanent control over the cosmos. It is the first Greek mythical cosmogony. The initial state of the universe is chaos, a dark indefinite void considered as a divine primordial condition from which everything else appeared. Theogony is a part of Greek mythology which embodies the desire to articulate reality as a whole; this universalizing impulse was fundamental for the first later projects of speculative theorizing.

Work and days is a didactic poem of some 800 verses written by the ancient Greek poet Hesiod around 700 BC. At its center, the Works and Days is a farmer's almanac in which Hesiod instructs his brother Perses in the agricultural arts. Scholars have seen this work against a background of agrarian crisis in mainland Greece, which inspired a wave of colonial expeditions in search of new land. In the poem Hesiod also offers his brother extensive moralizing advice on how he should live his life.
