aonian

AO'NIAN, a. [From aonia, a part of Boeotia, in Greece.]

Pertaining to the muses, or to Aonia in Boeotia. The Aonian fount was Aganippe, at the foot of mount Helicon, not far from Thebes, and sacred to the muses. Hence the muses were called Aonides. But in truth, Aonia itself is formed from the Celtic aon, a spring or fountain, [the fabled son of Neptune,] and this word gave name to Aonia. As the muses were fond of springs, the word was applied to the muses, and to mountains which were their favorite residence, as to Parnassus.
