“Maeve’s themes are fairies, magic, protection, leadership, and justice (law). Her symbols are birds and gold. As the Fairy Queen, Maeve oversees today’s merrymaking among the citizens of fey during their Fairy Gatherings. She also attends to human affairs by providing protection, wise leadership and prudent conventions. Works of art depict Maeve with golden birds on Her shoulders, whispering magical knowledge into Her ear.
Near the beginning of May, the wee folk of Ireland come out of hiding for a grand celebration of spring. If you don’t want the Maeve and the citizens of fey to pull pranks on you today, take precautions, as the Europeans do: avoid travelling, put a piece of clothing on inside-out, wear something red, and leave the fairy folk an offering of sweet bread, honey or ale. In some cases, this will please the fairies so much that they will offer to perform a service or leave you a gift in return!
When you need to improve your command of a situation or inspire more equity, call on Maeve through this spell:
Take a piece of white bread and toast it until it’s golden brown. Scratch into the bread a word or phrase representing your goal (for example, if raises at work haven’t been given fairly, write the words ‘work’ and ‘raises’). Distribute the crumbs from this to the birds so they can convey your need directly to Maeve’s ears.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Of the great female figures of Ireland, Maeve was probably the most splendid. Originally a Goddess of the land’s sovereignty and of its mystic center at Tara, She was demoted in myth, as the centuries went on and Irish culture changed under Christian influence, to a mere mortal queen.
But no mortal queen could have been like this one, this ‘intoxication’ or ‘drunken woman’ (variant meanings of Her name), who ran faster than horses, slept with innumerable kings whom She then discarded, and wore live birds and animals across Her shoulders and arms. If there ever was a woman named Maeve who reigned as queen of Ireland, it is probable that She was the namesake of the Goddess; the Goddess’s legends may have attached themselves to a mortal bearer of Her name.
Maeve is the central figure of the most important old Irish epic, the Tain Bo Cuillaigne, or Cattle Raid of Cooley. The story begins with Maeve, ruler of the Connaught wilderness in the Irish west, Iying abed with Her current consort, King Aillil. They compare possessions, Aillil attempting to prove he owns more than She does. Point for point, Maeve matches him. Finally, Aillil mentions a magical bull-and wins the argument, for Maeve has no such animal.
But She knows of one, the magic bull of Cooley in northern Eire. And so Maeve gathers Her armies to steal it. She rides into battle in an open car, with four chariots surrounding Her, for She is glamorously attired and does not wish to muddy Her robes. She is a fierce opponent, laying waste the armies of the land, for no man could look on Maeve without falling down in a paroxysm of desire.
The armies of Ulster, stricken with the curse of the Goddess Macha, fall down in labor pains upon the arrival of Queen Maeve’s army in their land. Only the hero Cuchulain resists, killing Locha, Maeve’s handmaiden, as well as many male heroes of Connaught. Maeve tries to buy victory with Her ‘willing thighs’, stops the battle whenever She is menstruating, and otherwise shows Herself to be an unusual warrior. After much bloodshed, She does indeed win Her bull–but it and Aillil’s bull fling themselves upon each other, tear each other to bits, and die in the bloodiest anticlimax in world literature.” 
“Medb (She who intoxicates) also known as Maev, Maeve, Maebh is a Celtic/Irish Goddess of Intoxication. Her body was the Earth; Her body processes were the Earth as it created. She was the force of the rushing waters, the windswept mountains, and the fertile plains. And, like many other deities, Medb is also associated with death as well as fertility and inebriation.
In the Irish mythological cycle, it was Medb who who who not only set the conditions for kingship, but also chose and tested Her partners, temporarily marrying those who passed Her tests. No king could accept the title unless She offered him the “Cup of Sovereignty”. She destroys those kings who spurn Her and has been know to send their warriors to their doom.
Medb is a triune Goddess who, in one of Her avatars, was able to assume human form and live among us mortals as a warrior queen; in fact, Medb is the most famous queen of Irish literature. She is often portrayed as a pale women with long flowing hair; She wears a red cape and carries a spear, while a raven and a squirrel are perched on Her shoulder.
She lived by violence and She died by violence. Her reign on Earth eventually came to an end as the result of Her murdering Her pregnant sister, Eithne (or Clothru). The baby managed to survive (her son Furbaide was born by posthumous caesarian section) and when he grew up, he revenged his mother by killing Medb.” 
“In Medb’s later years She often went to bathe in a pool on Inchcleraun (Inis Cloithreann), an island on Lough Ree. Furbaide took a rope and measured the distance between the pool and the shore, and practiced with his sling until he could hit an apple on top of a stake Medb’s height from that distance. The next time he saw Medb bathing he put his practice to good use and killed Her with a piece of cheese. She was succeeded to the throne of Connacht by Her son Maine Athramail.
According to legend, Medb is buried in a 40-foot (12 m) high stone cairn on the summit of Knocknarea (Cnoc na Ré in Irish) in County Sligo. Supposedly, She is buried upright facing Her enemies in Ulster. Her home in Rathcroghan, County Roscommon is also a potential burial site, with a long low slab named ‘Misgaun Medb’ being given as the most likely location.”
