Nemesia; Genesia/Nekysia, dedicated to Gaia and the dead: annual celebration in honor of the Forefathers and Ancestors. “Genesia: a funerary festival held by the Athenians, also known as Nekysia, in the course of which sacrifices were made to Gaia.”

“Beware of all the fifth days; for they are harsh and angry; it was on the fifth, they say, that the Erinyes assisted at the bearing of Horkos, whom Eris bore, to be a plague on those who take false oath.” “Shun the fifth days: i.e. the lunar days. We have heard from the Pythagoreans that the number five is number of Dike, and among them are told the causes of this..as She punishes all those who stray from the divine law, as told by Plato (Laws IV, 716a).”
Scholia to Hesiod, Erga, 802-804
