- The history and genealogy of demigods or heroes, especially the uncompleted history found in portions of Hesiod's Theogony.
- 1846, “Hsiodus”, in Dictionary of Greek and Roman Biography and Mythology, volume 2, page 442:
- […] the last portion, which is in fact a heroogony, being an account of the heroes born by mortal morthers whose charms had drawn the immortals from Olympus.
- 2010, Jon Bartley Stewart, editor, Kierkegaard and the Greek World: Aristotle and other Greek authors:
- The Theogony consists of a cosmogony, a theogony proper, and an unfinished heroogony.
- 2012, Gerard Naddaf, The Greek Concept of Nature: The Politics of Theory-Building and Pedagogy in Composition:
- Whether or not Hesiod added it himself, it should be no surprise that at the end of the Theogony there is a short heroogony (937f).
