Why is Tlachtga so named? It's not difficult.
History of Tlachtga
Tlachtga (was, in fact) the daughter of Mogh ruith, son of Fergus. Three sons of the magician Simon raped her. She had accompanied her father to learn the magical art of the world. For it was she who made the “Rolling Wheel” and the “Stone in Forcarthu” and the “Pillar in Cnamchaill” for Trian. She returned again from the east and brought the two things with her until she reached Tlachtga Hill. Indeed, it was there that she stopped and gave birth to three sons, namely Doirb, from whom the Doirb is named, and Cum(m)a, from whom the plain of Cuma and Muach from which comes the name of the plain of Muach and until these three names fell into oblivion in Ireland, the revenge of strangers will not torment her.
The hill of Tlachtga, splendid and high,
Fateful fate of a great and severe king,
From that moment Tlachtga called.
The daughter of King Roth's intelligent slave,
Mogh Roith, son of Fergus Fal,
The noble and royal son of Ross.
Cacht, the daughter of the bellicose Catmend
was his noble and remarkable mother.
Roth, son of Rigoll, was his nurturer.
This is why the name “Mogh Roith” was given to him.
Two sons of Mogh: Buan and Fer-Corb,
victorious over the armies in the acts of liberation.
She [Cacht] was the [foster] mother of step sons
From Der-Droighen, dark, strong and energetic,
And the real mother of Cairpre [Lifechair].
It is certain that he deceived the Hui-Bairdnes.
Mogh's daughter went with thousands,
Tlachtga, the chosen one – not that she was without feelings
To accompany his noble and great father,
Towards the proud Simon seven times splendid.
Three sons had Simon, pleasant to look at:
Painful his struggle against their devils.
*** powerful.
They were a powerful, passionate and determined family.
The [three] sons fell in love with Tlachtga at the same time,
They begot in her – it's no lie
a beautiful and noble descent.
For Trian – without taking any glory from it –
Tlachtga created the moving red wheel,
With the great and noble Mogh [Ruith],
And with Simon seven times splendid.
She returned with the wise words;
She brought the moving wheel,
The perfect stone of Forcarthu she brought,
And the pillar of Cnamchaill.
Whoever sees her will become blind,
Whoever hears it will become deaf,
And anyone who tries to take a piece
From the wheel with the sharp spokes will die ***
When the woman returned from the East,
She gave birth to three sons with difficulty.
She died, the bright and lively woman.
It was necessary to hear this incelable news.
The names of the sons were of great importance ***
Muach and Cuma and Doirb the Noble.
The crowd ***
for it is fitting that they should hear it:
As long as across majestic Banba [Ireland]
The names of the three sons are preserved
As the true story goes***
No disaster will befall its inhabitants.
The hill where the grave was erected
for the woman of the East, who is not negligible;
Without error, melodious and unparalleled,
Here is the name given to it:
Tlachtga hill.
