There are four great festivals of the Pagan Celtic year and the modern Witch's calendar, as well. The two greatest of these are Halloween (the beginning of winter) and May Day (the beginning of summer). Being opposite each other on the wheel of the year, they separate the year into halves. Halloween (also called Samhain) is the Celtic New Year and is generally considered the more important of the two, though May Day runs a close second. Indeed, in some areas -- notably Wales -- it is considered the great holiday.
May Day ushers in the fifth month of the modern calendar year, the month of May. This month is named in honor of the goddess Maia, originally a Greek mountain nymph, later identified as the most beautiful of the Seven Sisters, the Pleiades. By Zeus, she is also the mother of Hermes, god of magic. Maia's parents were Atlas and Pleione, a sea nymph.
The old Celtic name for May Day is Beltane (in its most popular Anglicized form), which is derived from the Irish Gaelic 'Bealtaine' or the Scottish Gaelic 'Bealtuinn', meaning 'Bel-fire', the fire of the Celtic god of light (Bel, Beli or Belinus). He, in turn, may be traced to the Middle Eastern god Baal. By Celtic reckoning, the actual Beltane celebration begins on sundown of the preceding day, April 30, because the Celts always figured their days from sundown to sundown. And sundown was the proper time for Druids to kindle the great Bel-fires on the tops of the nearest beacon hill (such as Tara Hill, Co. Meath, in Ireland). These 'need-fires' had healing properties, and sky-clad Witches would jump through the flames to ensure protection.

Frequently, cattle would be driven between two such bon-fires (oak wood was the favorite fuel for them) and, on the morrow, they would be taken to their summer pastures.


Other May Day customs include: walking the circuit of one's property ('beating the bounds'), repairing fences and boundary markers, processions of chimney-sweeps and milk maids, archery tournaments, morris dances, sword dances, feasting, music, drinking, and maidens bathing their faces in the dew of May morning to retain their youthful beauty.
In the words of Witchcraft writers Janet and Stewart Farrar, the Beltane celbration was principly a time of '...unashamed human sexuality and fertility.' Such associations include the obvious phallic symbolism of the Maypole and riding the hobby horse. Even a seemingly innocent children's nursery rhyme, 'Ride a cock horse to Banburry Cross...' retains such memories. And the next line '...to see a fine Lady on a white horse' is a reference to the annual ride of 'Lady Godiva' though Coventry. Every year for nearly three centuries, a sky-clad village maiden (elected Queen of the May) enacted this Pagan rite, until the Puritans put an end to the custom.


The Puritans, in fact, reacted with pious horror to most of the May Day rites, even making Maypoles illegal in 1644. They especially attempted to suppress the 'greenwood marriages' of young men and women who spent the entire night in the forest, staying out to greet the May sunrise, and bringing back boughs of flowers and garlands to decorate the village the next morning. One angry Puritan wrote that men 'doe use commonly to runne into woodes in the night time, amongst maidens, to set bowes, in so muche, as I have hearde of tenne maidens whiche went to set May, and nine of them came home with childe.' And another Puritan complained that, 'Of forty, threescore or a hundred maids going to the wood over night, there have scarcely the third part of them returned home again undefiled.'
Long after the Christian form of marriage (with its insistance on sexual monogamy) had replaced the older Pagan handfasting, the rules of strict fidelity were always relaxed for the May Eve rites. Names such as Robin Hood, Maid Marion, and Little John played an important part in May Day folklore, often used as titles for the dramatis personae of the celebrations. And modern surnames such as Robinson, Hodson, Johnson, and Godkin may attest to some distant May Eve spent in the woods.
Some of these customs seem virtually identical to the old Roman feast of flowers, the Floriala, three days of unrestrained sexuality which began at sundown April 28th and reached a crescendo on May 1st.
There are other, even older, associations with May 1st in Celtic mythology. According to the ancient Irish 'Book of Invasions', the first settler of Ireland, Partholan, arrived on May 1st; and it was on May 1st that the plague came which destroyed his people. Years later, the Tuatha De Danann were conquered by the Milesians on May Day. In Welsh myth, the perenial battle between Gwythur and Gwyn for the love of Creudylad took place each May Day; and it was on May Eve that Teirnyon lost his colts and found Pryderi. May Eve was also the occasion of a fearful scream that was heard each year throughout Wales, one of the three curses of the Coranians lifted by the skill of Lludd and Llevelys.
