Bessed Lammas to all
Heres a little story for you
Lug or Lugh /luɣ/; modern Irish: Lú /lu:/) is an Irish deity represented in mythological texts as a hero and High King of the distant past. He is known by the epithets Lámhfhada (pronounced /'la:wad ̪ ˠə/, meaning "long arm" or "long hand"), for his skill with a spear or sling, Ildánach ("skilled in many arts"), Samhildánach ("Equally skilled in many arts"), Lonnbeimnech ("fierce striker" or perhaps "sword-shouter") and Macnia ("boy hero"), and by the matronymic mac Ethlenn or mac Ethnenn ("son of Ethliu or Ethniu"). He is a reflex of the pan-Celtic god Lugus, and his Welsh counterpart is Lleu Llaw Gyffes, "The Bright One with the Strong Hand".

Lugh's name and nature
Sacred sites in Ireland
Lugh's father is Cian of the Tuatha Dé Danann, and his mother is Ethniu, daughter of Balor, of the Fomorians. In Cath Maige Tuired their union is a dynastic marriage following an alliance
between the Tuatha Dé and the Fomorians.  In the Lebor Gabála Érenn Cian gives the boy to
Tailtiu, queen of the Fir Bolg, in fosterage. 
A folktale told to John O'Donovan by Shane O'Dugan of Tory Island in 1835 recounts the birth of a grandson of Balor who grows up to kill his grandfather. The grandson is unnamed, his father is called Mac Cinnfhaelaidh and the manner of his killing of Balor is different, but it has been taken as a version of the birth of Lugh, and was adapted as such by Lady Gregory. In this tale, Balor hears a druid's prophecy that he will be killed by his own grandson. To prevent this he imprisons his only daughter in the Tór Mór (great tower) of Tory Island, cared for by twelve women, who are to prevent her ever meeting or even learning of the existence of men. On the mainland, Mac Cinnfhaelaidh owns a magic cow who gives such abundant milk that everyone, including Balor, wants to possess her. While the cow is in the care of Mac Cinnfhaelaidh's brother Mac Samthainn, Balor appears in the form of a little red-haired boy and tricks him into giving him the cow. Looking for revenge, Mac Cinnfhaelaidh calls on a leanan sídhe (fairy woman) called Biróg, who transports him by magic to the top of Balor's tower, where he seduces Eithne. In time she gives birth to triplets, which Balor gathers up in a sheet and sends to be drowned in a whirlpool. The messenger drowns two of the babies, but unwittingly drops one child into the harbour, where he is rescued by Biróg. She takes him to his father, who gives him to his brother, Gavida
the smith, in fosterage. 
There may be further triplism associated with his birth. His father in the folktale is one of a triad of brothers, Mac Cinnfhaelaidh, Gavida and Mac Samthainn, and his father in the medieval texts, Cian, is often mentioned together with his
brothers Cú and Cethen.  Two characters called Lugaid, a popular medieval Irish name thought to derive from Lugh, have three fathers: Lugaid Riab nDerg (Lugaid of the Red Stripes) was the
son of the three Findemna or fair triplets,  and Lugaid mac Con Roí was also known as mac Trí
Con, "son of three hounds".  In Ireland's other great "sequestered maiden" story, the tragedy of Deirdre, the king's intended is carried off by
three brothers, who are hunters with hounds. 
The canine imagery continues with Cian's brother Cú ("hound"), another Lugaid, Lugaid Mac Con (son of a hound), and Lugh's son
Cúchulainn ("Culann's Hound").  A fourth Lugaid was Lugaid Loígde, a legendary King of Tara and ancestor of (or inspiration for) Lugaid Mac Con.
Lugh joins the Tuatha Dé Danann
As a young man Lugh travels to Tara to join the court of king Nuada of the Tuatha Dé Danann. The doorkeeper will not let him in unless he has a skill with which to serve the king. He offers his services as a wright, a smith, a champion, a swordsman, a harpist, a hero, a poet and historian, a sorcerer, and a craftsman, but each time is rejected as the Tuatha Dé Danann already have someone with that skill. But when Lugh asks if they have anyone with all those skills simultaneously, the doorkeeper has to admit defeat, and Lugh joins the court and is appointed Chief Ollam of Ireland. He wins a flagstone-throwing contest against Ogma, the champion, and entertains the court with his harp. The Tuatha Dé are at that time oppressed by the Fomorians, and Lugh is amazed how meekly they accept this. Nuada wonders if this young man could lead them to freedom. Lugh is given command over the Tuatha Dé, and he begins
making preparations for war. 
The sons of Tuireann
When the sons of Tuireann, Brian, Iuchar and Iucharba, kill his father, Cian (who was in the form of a pig at the time), Lugh sets them a series of seemingly impossible quests as recompense. They achieve them all, but are fatally wounded in completing the last one. Despite Tuireann's pleas, Lugh denies them the use of one of the items they have retrieved, a magic pigskin which heals all wounds. They die of their wounds, and Tuireann dies of grief over
their bodies. 
The Battle of Magh Tuireadh
Using the magic artifacts the sons of Tuireann have gathered, Lugh leads the Tuatha Dé Danann in the Second Battle of Mag Tuireadh against the Fomorians. Nuada is killed in the battle by Balor. Lugh faces Balor, who opens his terrible, poisonous eye that kills all it looks upon, but Lugh shoots a sling-stone that drives his eye out the back of his head, wreaking havoc on the Fomorian army behind. After the victory Lugh finds Bres, the half-Fomorian former king of the Tuatha Dé, alone and unprotected on the battlefield, and Bres begs for his life. If he is spared, he promises, he will ensure that the cows of Ireland always give milk. The Tuatha Dé refuse the offer. He then promises four harvests a year, but the Tuatha Dé say one harvest a year suits them. But Lugh spares his life on the condition that he teach the Tuatha Dé how and
when to plough, sow and reap. 
Later life and death
Lugh instituted an event similar to the Olympic games called the Assembly of Talti which finished on Lughnasadh (1 August) in memory of his foster-mother, Tailtiu, at the town that bears her name (now Teltown, County Meath). He likewise instituted Lughnasadh fairs in the areas of Carman and Naas in honour of Carman and Nás, the eponymous tutelary goddess of these two regions. Horse races and displays of martial arts were important activities at all three fairs. However, Lughnasadh itself is a celebration of Lugh's triumph over the spirits of the Other World who had tried to keep the harvest for themselves. It survived long into Christian times and is still celebrated under a variety of names. Lúnasa is now the Irish name for the month of August.
According to a poem of the dindsenchas, Lugh was responsible for the death of Bres. He made 300 wooden cows, and filled them with a bitter, poisonous red liquid which was then "milked" into pails and offered to Bres to drink. Bres, who was under an obligation not to refuse hospitality, drank it down without flinching, and
it killed him. 
Lugh is said to have invented the board game fidchell. He had a dog called Failinis.
He had several wives, including Buí and Nás, daughters of Ruadri, king of Britain. Buí lived and was buried at Knowth. Nás was buried at Naas, County Kildare, which is named after her. Lugh
had a son, Ibic, by Nás.  His daughter or sister was Ebliu, who married Fintan. One of his wives, unnamed, had an affair with Cermait, son of the Dagda. Lugh killed him in revenge, but Cermait's sons, Mac Cuill, Mac Cecht and Mac Gréine, killed Lugh in return, drowning him in Loch Lugborta. He had ruled for forty years.
