The Triple Goddess Symbol

Recently I have been approached from a member who asked what this symbol means ')O('
Here goes, all will be told in this forum.

In ancient Indo-European mythologies, various goddesses or demi-goddesses appear as a triad, either as three separate beings who always appear as a group (the Greek Moirae, Charites, Erinnyes and the Norse Norns) or as a single deity who is commonly depicted in three aspects (Greek Hecate and the cult image of Latin Diana Nemorensis, of whom Hecate is one part [1] ). Often it is ambiguous whether a single being or three are represented, as is the case with the Irish Brighid and her two sisters, also called Brighid, or the Morrígan who is known by at least three or four different names. In most ancient portrayals of triple goddesses, the separate deities perform different yet related functions, and there is no obvious difference in their ages.
In Wicca and related Neo-pagan religions, the Triple Goddess is, along with the Horned God, held in particular reverence, and her three aspects are most often portrayed as being of different ages: Maiden, Mother and Crone.
A Triple Goddess symbol (probably originating from Classical Greek lunar symbolism), depicting three phases of the moon: waxing crescent, full moon, and waning crescent.

Some sayings from different takes of the Triple Goddess meaning.

... they call You Hekate,
Many-named, Mene, cleaving Air just like
Dart-shooter Artemis, Persephone,
Shooter of Deer, night shining, triple-sounding,
Triple-headed, triple-voiced Selene
Triple-pointed, triple-faced, triple-necked,
And Goddess of the Triple Ways, who hold
Untiring Flaming Fire in Triple Baskets,
And You who oft frequent the Triple Way
And rule the Triple Decades...

******************************

...Mother of Gods
And Men, and Nature, Mother of All Things...
...Beginning
And End are You, and You Alone rule All.
For All Things are from You, and in You do
All Things, Eternal One, come to their End.

Diana in the leavës green,
Luna that so bright doth sheen,
Persephone in Hell.
