Hesiod lived approximately in the 8th century BC and is considered one of the pillars of ancient Greek poetry. He is believed to have been born in Cyme, a city in Aeolia, Asia Minor, but spent much of his life in Ascra, Boeotia, mainland Greece. This geographical distinction, along with the possibility of homonyms, has led to debates about his exact life and the authorship of certain works. His most celebrated work, "Theogony", is a detailed narrative of the genealogy of the Greek gods, from the primordial Chaos to the establishment of the Olympian order under Zeus. It is a primary source for the study of Greek mythology. "Works and Days" is a didactic and moral poem, where Hesiod advises on hard work, agriculture, justice, and ethical living. The poem also contains the famous myth of the five ages of man, describing the decline of humanity. Other works attributed to Hesiod include "Catalogue of Women" and "The Shield of Heracles", although their authorship is less certain. Hesiod offers a valuable glimpse into the society, beliefs, and values of Archaic Greece, contrasting with the epic and heroic nature of Homeric poetry. His more personal and reflective approach distinguishes him as one of the first poets to express an individual voice in Western literature.
