The history and genealogy of demigods or heroes, especially the uncompleted history found in portions of Hesiod's Theogony.
1846,“Hsiodus”, inDictionary 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).
