The Muses are the Greek goddesses who preside over the arts
and sciences and inspire those who excel at these pursuits. Daughters
of Zeus and Mnemosyne ("memory"), they were born in Pieria on the
foot of Mount Olympus. Their nurse, Eupheme, raised them alongwith her son, Crotus the hunter , who was transported into the sky as
Sagittarius upon his death. Their name denotes 'memory' or 'a reminder', since in earlier times poets having no books to read from,
The original number of muses and their names vary. At first,
three muses were worshipped on Mount Helicon in Boeotia: Melete
("meditation"), Mneme ("memory"), and Aoede ("song"). Another three were worshipped at Delphi and their names represented the names of the strings of a lyre: Nete, Mese, and Hypate. The Greeks believed there were nine muses, each providing over some form of literature, art, or science. There was Calliope, as well as Clio the muses of history, Euterpe of lyric poetry, Melpomene of tragedy, Terpsichore of choral dance and song, Erato of love poetry, Polyhymnia of sacred poetry, Urania of astronomy, and Thalia of comedy (Encyclopedia Mythica). The Muses had several titles which usually referred to places where they had settled. Ephialtes and Otus, who also founded Ascra, were the first to sacrifice on Helicon to the Muses and to call the mountain sacred to the Muses. Sacrifices to the Muses consisted of gifts of water, milk, or honey.

In Plato's Phaedrus 259c, Socrates says that locusts were men
before the birth of the Muses. When the Muses were born, some men
were so overcome with delight that they sang constantly, forgetting to
eat or drink until they eventually died. These men became locusts with
a gift from the Muses allowing them to sing continuously from their
birth until death without the need of sustenance.

The Muses could also have been seen as vindictive. This was
seen in the story of the contest with Thamyris. Thamyris who excelled
all of them. The Muses won the contest, and deprived Thamyris of his

Cissa, Chloris, Acalanthis, Nessa, Pipo, and Dracontis(Graves 170.q) .
