Alcyone and Ceyx

It is also speculated that Alkyóne is derived from alké (ἀλκή, "prowess, battle, guard") and onéo (ὀνέω, from ὀνίνεμι, onínemi,[6] "to help, to please").

[11] She was the sister of Salmoneus, Athamas, Sisyphus, Cretheus, Perieres, Deioneus, Magnes, Calyce, Canace, Pisidice and Perimede.

On the contrary, it is mentioned that while still unaware of Ceyx's death in the shipwreck, Alcyone continued to pray at the altar of Hera for his safe return.

Pseudo-Probus, a scholiast on Virgil's Georgics, notes that Ovid followed Nicander's version of the tale, instead of Theodorus's starring another Alcyone.

The expression ἀλκῠονίδες ἡμέραι (alkuonídes hēmérai) first occurs in Aristophanes' play The Birds 1594, then again in Aristotle, Philochorus, and Lucian.

[20] In Latin it occurs as alcyonides dies in Pliny the Elder, alcyonei (-nĭī) diēs in Columella and Varro, alcyonia in Hyginus, and alcedonia in Plautus and Frontinus.
