The Muses were deities worshipped by the ancient Greeks. They were 9 women, sisters, whose sole purpose for being was that of the inspiration to mortal man, typically in an artistic capacity. The embodiment of the classical idea of the poetical faculty as a divine gift, these famous sisters dwelt on Mount Helicon, in Greece. The Muses were therefore both the embodiments and sponsors of performed metrical speech: mousike, whence "music", was the art of the Muses. (nationbuilder) They were the “personification of poetic inspiration, the divine afflatus or breath which supposedly wafted itself into the poet's inflamed mind”. The Muses of Greek mythology had one of the most important functions of all: to inspire poets and promote the arts and sciences. The fortunate person inspired by them was held in the highest esteem and considered sacred far beyond any priest. (mythman)
The nine Muses are the daughters of the Zeus and of Mnemosyne the goddess of memory. Mnemosyne slept with Zeus nine consecutive nights and gave birth to nine daughters. Interestingly, according to Pausanias , a Greek traveler, geographer, and writer of the 2nd century AD, there were only three original Muses: Aoide ("song", "voice"), Melete ("practice" or "occasion") and Mneme ("memory") . These 3 were thought to be fathered by Apollo. However, by classical times their number was set at nine, and Zeus was noted as their father. In this context the god dearest to them was Apollo and they were his faithful followers. The Muses revered him. For these reasons he is often called the Musegetes, which means "Leader of the Muses".
Pierus the Macedonian, from whom the mountain Macedonia is named came to Thesbia and ordered that the Muses be worshipped by the names they have at present: Euterpe; Calliope; Clio; Erato; Melpomene; Polyhymnia; Terpsichore; Thalia; and Urania. The muses themselves, as part of Greek mythology have many stories written about them.The
