My most recent version of Chamber’s Book of Days  tells us that:
This is All-Hallows Eve, better known as Hallowe’en, when witches fly abroad and ghosts, fairies, evil spirits and other supernatural beings are at their most active. The traditional beliefs and practices of Hallowe’en may be connected in origin with the rituals performed during the night before Samhain.
The 1864 edition of Chambers said:
Great fun goes on in watching the attempts of the youngster in the pursuit of the swimming fruit, which wriggles from side to side of the tub, and evades all attempts to capture it; whilst the disappointed aspirant is obliged to abandon the chase in favour of another whose turn has now arrived. The apples provided with stalks are generally caught first, and then comes the tug of war to win those which possess no such appendages. Some competitors will deftly suck up the apple, if a small one, into their mouths. Others plunge manfully overhead in pursuit of a particular apple, and having forced it to the bottom of the tub, seize it firmly with their teeth, and emerge, dripping and triumphant, with their prize.
So – what is the ‘real’ story?
The last night of October; Old Year’s Night in the Celtic calendar; was a night of witches and fires that was changed by the Church into the vigil of All Saints’ or Hallowe’en.
‘Teanlas’ or ‘tinley’ fires would glow on northern hills on All Souls’ Eve, symbolising the ascent to heaven of souls in purgatory. It was only the introduction of farming enclosures, when bushes were grubbed up, that put an end to the small ‘tindles’, lighted in the furze of Derbyshire commons.
In one Lancashire field, called Purgatory by the old folk, men stood in a circle to throw forkfuls of burning straw high in the air on the night breeze, and all present fell to their knees praying for the souls of the departed. More prosaically – some farmers maintained that the procedure was useful against weed ‘darnel’.
Samhain is a Gaelic festival marking the end of the harvest season and the beginning of winter or the “darker half” of the year. The Celtic day began and ended at sunset so it was traditionally celebrated through the 31st October to 1st November – a time that is about halfway between the autumn equinox and the winter solstice.
That’s it – there’s nothing for me to add apart from just saying:
HAVE A GREAT TIME ON THIS HALLOWE’EN
