I have a little ritual of course when I visit stones. I take a little quartz stone (that represents my troubles) and leave it at the base of the monument, give it back to the earth so to speak. Then I simply touch the megalith and bring some of its stalwart presence away home with me for the next while. Sometimes I put in a mighty effort, deliberately seeking out sunrise aligned sites, other times sunset ones, depending on my mood and the weather. Although I am convinced every standing stone is aligned with something so it is of no consequence. (I've been known to drive to Wicklow for the sunrise)
The stone in question, which is outstanding in its field, (boom boom) is in my neighbouring townland of Ballinvir. “There stands here, in a fence, a pillar stone of large size and remarkable appearance.”  This standing stone may in fact be the place where the Druid Ferchais killed the High King Lughaid Mac Con. This one though is particularly fascinating. It is an intriguingly simple monument, in the shadow of Slievenamon. It is easily accessible from a public road, just a little climb over a gate really. The druid in me knows that it is special and the amateur archaeologist in me deigns it impossible to ascertain its alignment to a landmark or other site, the light being too low on a cloudy day. There is a lovely ash plantation in a neighbouring field and Slievenamon is just there. It seems to have cup marks, which might just simply be erosion and probably is. They could be spear marks too. In Gaelic it is “Bhaile an Bhioraigh” translated as “Town of the morass.” 
When it comes to standing stones it is safe to assume that they are not just erratic glacial scree (though not always) and that they did not grow out of the ground whereupon they stand. They were placed there by persons unknown and for a reason. Some mark boundaries, others milking places, some have a ritual purpose, some are oath stones, other stones like the Lia Fáil for example even speak. So it is safe to say all of them have a useful application. We know of “Roan Rí Oilech i.e. a king (rí) that put rocks (aile) of stones into menhirs, and he got the name Aillech from the rocks of stones which were put by him into menhirs. Hence Aillech 'rocky' was said of him.” 
I'd no sooner traversed the gate when I was startled by the crack of gunshot. Now the landowner knows of my fascination and he has no problem with me visiting, so I wasn’t concerned about being chased off the land. And I have been chased off land, called a banshee etc, but that is another story. Some gobshite was hunting game, or culling deer or target practicing for some subversive organisation. I found a button here once with the French Foreign Legion insignia on it.
This stone is situated close to an ancient highway that ran from Magh Femhin via the Gap of Rath Clarish to Newtown Lennan and the Deise. It is close to a site recorded in the annals as Athnacarbed known today as Templemichael. In the Visitations of Elizabeth the church of Athnacarbad is twice placed between Grangemockler and Newtown Lennon.
Who was Lughaid Mac Con? And why do I think this is the place where he might have met his demise at the hands of Ferchais the Druid? The Dáirine were rulers of Munster before the rise of the Eóganachta in the 7th century AD. According to the Táin Bó Flidais, they were one of the three warrior-races (Laech-Aicmi) of Ireland. Mac Con had a noble pedigree, his mother Sadb (ingen) Chuinn was a daughter of Conn of the Hundred Battles, a High King of Ireland. Her brother was Art (mac) Cuinn, also became a High King of Ireland, while her sister Sáruit married Conaire Cóem of the Érainn, who was High King before him. Sadb is described as "one of the four best women that man ever lay with".  His father was Macnia mac Lugdach, prince of the Dáirine.
After Macnia died, Sadb married Ailill Aulom, (Ailill of the one ear) king of Munster. He was the son of Mug Nuadat and king of the southern half of Ireland in the 3rd century. One fine summer after a drought he was short of grass. Fearing the loss of his herds and starvation he consulted the Druids. Ferchais suggested he go to Knockainey at Samhain Eve a site associated with harvest and Lugh and the Goddess Áine of plentiful crops and fertility. He forced himself upon her, as defence she bit off his ear, and thus his nickname Aulum "one-eared". A king was required to be “unblemished" and by maiming him so, Áine rendered him unfit to be king. Ailill retaliated and thrust his five-barbed poisoned spear at her and drove it through her to the ground killing her. The spear struck a stone and thus became bent and he tried to straighten it with his teeth.
It was forbidden to strike a woman with a spear, or strike a stone with a spear or to place it under a tooth in order to straighten it. All of these things were taboo. The poison in the barb of the spear entered Ailill's tooth and did him great harm, corrupting his breath, and blackened his tooth, and he had a poisonous tooth thereafter. It is said that he nearly went mad from the venom and definitely went blind. He lived to a good old age nonetheless, thirty years before he became king, thirty years in kingship, and thirty years after his kingship.
He divided the kingdom between his sons Éogan Mór, Cormac Cas, and Cian. Éogan founded the dynasty of the Eóganachta. Sadb's son Lugaid mac Con, Ailill's foster-son, became High King of Ireland. Lugaid Mac Con’s name translates as “Hound’s son”. There lived a hound named Eloir the Red in Ailill’s homestead. As a baby Lugaid crawled around after the hound and would nuzzle up against its belly and that is how he earned that name.
There was a covenant between Lugaid and Ailill Aulum and between their offspring after them that whenever Aulum's offspring held the kingship, Lugaid's offspring should hold the judgeship; but when Lugaid's offspring held the kingship, Aulum's sons were to hold the judgeship. Lugaid and Ailill made this arrangement in the presence of Conn of the hundred battles over one half of Ireland. Thus the men of Leinster and Munster held kingship and judgeship. “Over one half of Ireland, that is to say, over Leinster and Munster, they held kingship and judgeship.” 
Mac Con reigned for thirty years when he first became king with his step brothers as allies. He was a noted warrior; “It was heavy work to wage an equal battle with Mac Con; there was no one in Ireland with his splendour.”  He killed his step brothers, the seven sons of Ailill, and his mother’s brother, Art son of Conn, in the battle of Mucrime. They found a musical instrument at a waterfall in Ess Mage. This instrument, a harp had threads of silver and pegs of gold, and they fight between them for the possession of this harp with Lugaid the victor. He was exiled from Ireland for this indiscretion and spent seven years in Alba.
While there he formed an alliance with Benne Brit, the King of Britain’s son and raised an army and returned home. During the Battle of Maigh Mucruimhe he killed Art and became High King. He ruled for a further thirty years until he was ousted by Art’s son Cormac, after which he sought refuge back in Munster with his own people.
Not quite forgiven by his foster father Ailill Aulom, Mac Con was bitten by his poison tooth as they embracedat their reunion. His mother counseled him to leave. Ferchais was despatched to take revenge on him for having killed Éogan Mór. Ferchis found Lugaid Mac Con standing with his back to a standing stone near Athnacarbad, and killed him with a spear.
In the Visitations of Elizabeth the church of Athnacarbad is twice placed between Grangemockler and Newtown Lennon. This is thought to be the modern day Templemichael close to the Ballinvir menhir. . Mac Con had two sons, Fothad Cairpthech and Fothad Airgthech, who would later be joint High Kings. It is entirely likely that this is the stone where Mac Con met his fate; it is most certainly a contender. Either way, it is a fine stone and I left my troubles there.
