#athena celebrations

Δευτέρα Ἱσταμένου, II day
From today’s sunset: second day of Boedromion.
The second day is always sacred to the Agathos Daimon, to all the Heroes and Heroines and to the Chthonian Deities. It is also a day sacred to Poseidon.

Niketeria, celebrating the victory of Athena over Poseidon in the contest for the possession of Attica.
“You who obtained the Acropolis on the high-crested hill,
a symbol, Queen, of the top of your great series;
You who loved the man-feeding land, mother of books,
strongly resisting the holy desire of your father’s brother,
and granted the city to have your name and noble mind-
there, under the top edge of the mountain, You made an olive tree
sprout up as a manifest sign of that battle for posterity too,
when an immense gulf stirred up from the sea
came upon the children of Cecrops, directed by Poseidon,
lashing all things with its loud-roaring streams.”
Proclus’ Hymn to Athena

“Even now the victory of Athena is celebrated by the Athenians; they have a festival because Poseidon has been surpassed by Athena, because the order of generation has been overpowered by the noeric one and because the inhabitants of that region, after the necessary things had been taken care of, rushed toward the intellectual life. For Poseidon is considered to be the Leader of generation, while Athena is the Guardian of the noeric life.”
Proclus, in Tim., 53d
