The Theogony "the genealogy or birth of the gods" is a poem by Hesiod (8th – 7th century BC) describing the origins and genealogies of the Greek gods, composed c. 730–700 BC. It is written in the Epic dialect of Ancient Greek and contains 1022 lines. 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 known Greek mythical cosmogony.

The Greek poet, Hesiod, stands out as the first personality in European literature. The Theogony contains a genealogy of the gods from the beginning of time and an account of their violent struggles before the present order was established. The Works and Days, a compendium of advice for a life of honest husbandry, shines a unique and fascinating light on archaic Greek society, ethics, and superstition. Hesiod's poetry is the oldest source of the myths of Prometheus, Pandora, and the Golden Age.

The earliest surviving works of ancient Greek literature, dating back to the early Archaic period, are the two epic poems the Iliad and the Odyssey. These two epics, along with the Homeric Hymns and the two poems of Hesiod, Theogony and Works and Days, comprised the major foundations of the Greek literary tradition that would continue into the Classical, Hellenistic, and Roman periods. This carefully selected collection contains: The Odyssey ; The Works and Days ; Theogony ; The Complete Poems of Sappho ; Medea ; Antigone ; Agamemnon ; The Choephori ; Eumenides.

"The Theogony" (“Birth of the Gods”) is a poem by Hesiod which describes the origin, position and relationships of the gods of the Greek pantheon. Hesiod created a synthesis of the diverse Greek traditions concerning the gods, in the form of a hymn invoking Zeus and the Muses. The Theogony is the first known Greek mythical cosmogony. However, it should not be considered as the authoritative source of Greek mythology, but rather as a portrait of a dynamic tradition that was recorded around 700 BCE.

Among the finest poets of ancient Greece was Hesiod, a contemporary of Homer, who lived in the eighth century B.C. It is still a matter of dispute whether Homer or Hesiod was the earlier poet, and sometimes whether they were one and the same person! At any rate, Hesiod's incredible poetry serves as a major source for our understanding of Greek mythology, farming practices, time keeping and astronomy. In and of itself, the "Works and Days" is unparalleled in its richness and beauty, easily rivaling Homer.
