The ‘club’ of the Cailleach was an interesting metaphorical tool that seems to have informed many Atlantic pagan seasonal traditions… In summer (from Beltain to Lúnasa – the season of the constellations Virgo and Taurus) it represented either a ‘sprouting branch’ (traditionally held by the character depicted in Virgo), the drover’s ‘cow-switch’ or the shepherd’s ‘crook’. The ancient Irish word for a cowherd – búachaill – is very similar to that in other Celtic and Indo-European languages (eg – Greek = βουκόλος = boukolos). It is also used adjectivally (as buachalan) to mean ‘cow-switch’ or in modern times, as a class-word for any useful tool. It also became a class-word for stalky plant species: Buachalan Bui is the Ragwort (Senecio Jacobea) and Buachalan Ban (Manx: Bollan Bane) was used for Mugwort (Artemisia Vulgaris): Both make excellent cattle-switches as it happens, and it is desirable to pull up the former from pastures as it harms cattle. The Manx Bollan Bane is the traditional herb associated with the Julian Calendar midsummer celebration of Tynwald Day in the Isle of Man: Old English herbals refer to it as ‘Motherwort’ and it was used as a protective charm against miscarriage (nature’s womb is ripening at midsummer when the Artemisia flowers). Stalky plants (cuiseόg – ‘fairy dogs’?) of this type are notable as they leave their ‘bones’ or ‘ghosts’ standing dry in the winter landscape, whereas more tender vegetation tends to compost. The Artemisia, the Senecio and other plants of the Gaelic cuiseόg class (including the umbilliferae including Hemlock, Cow Parsley etc) were given superstitious associations with fairies and ‘witches’ in folklore.

‘Vervain and Dill hinder witches of their will’ (English tradition quoted by early folklorist John Aubrey, 1721) – the stalky plants whose shapes survive in the winter landscape (in spite of a ‘beating’ by the ‘goddess’) often had a superstitious reputation in folklore.
In harvest the ‘club’ might represent the reaping sickle or threshing flail. In fact, harvest is the start of autumn and plants are usually spent of their generative power when they have fruited. They give life and seem to die back – so it is perhaps no surprise that the Cailleach theology gave her a ‘club’ by which she might beat vegetation back and give new life simultaneously.

Children in the Isle of Man (and elsewhere) used to be told not to pick and eat blackberries after 10th October (Old Michaelmas by the Julian calendar) as the ‘Devil’ was supposed to have touched them with his ‘club’ and turned them sour.
In summer the Cailleach’s functioned as a ‘cattle-switch’, but its use is now turned to a more destructive cause. There is a subtle juxtasposition of violence and new life inherent in this, which shows through in a number of ancient Atlantic traditions with pagan associations:

Shillelaghs – cut from the hardwood of Blackthorn or Oak, they make formidable weapons … or Hurling sticks!
In the wren-hunts (Isle of Man, Ireland etc), a stave was the weapon of choice used to hunt and kill this hapless tiny avian – apparently a representation of the Goddess. Once dead, its body was typically hoisted up on a pole, festooned in ribbons and greenery (sometimes even crucified) and paraded about… A simple club-stick with a crook or hook on the end was the original weapon of the related ancient traditional combative mid-winter stick-and-ball games played in the Gaelic lands: Shinty (Scots Gaelic: Camanachd, iomain), Cammag (the Manx version) and Hurling (Irish: Iománaíocht/Iomáint, played with a stick called a camán). These rough games were often held in conjunction with the wren-hunts in times gone by, and there is another interesting link to the Cailleach (who was depicted as one-eyed, crooked and ancient): The Gaelic word ‘Cam’ means ‘crooked’, ‘twisted’ or ‘deformed’ as well as being formerly applied as a description of a person as ‘one-eyed’…

A modern depiction of the Cailleach Bheur (‘Hag of Winter’) of Scottish Highland legend. She carried a hammer or staff to beat the vegetation back into the ground in the cold months.
At some of the Lúnasa/Lughnasadh fairs and hilltop gatherings in Ireland, sticks used to be the weapon of choice in traditional faction fights, and it is of note that a long shillelagh might easily double up as a cáman for Hurling or one of its related cousins. The mythological Irish warrior Cúchulainn is described as playing at hurling in the Táin Bó Cúailnge, and is even said in some versions to have killed the hound of ‘Chulainn the Smith’ (possibly a deliberate corruption of Caillean/Cailleach!) with a hurling-ball (sliotar) providing an etymology for his name! The theme of combat and the Morrigan underpins the whole of the Tain, many of the battles of which occur at river fords – bringing to mind the image of Orion standing next to the Milky Way, near Taurus, the ‘Dog Star’ and Canis Minor, not far from the wren-like twinkling stars of the Pleiades or ‘Seven Sisters’…
