But we have got to the tenth century, and the two youthful brothers destined to give a disabling blow to Danish tyranny are learning the profession of arms in their father's fortress in Thomond, (Tuaith Muimhain, North Munster.) These were Mathgamhain [Footnote 280] and Brian, sons of Cennedigh, (Kennedy,) chief of the tribe of Dal-Cais.

[Footnote 280: However the people of the tenth century pronounced this word, modern scholars are content to sound it Mahoun.
An old Munster king, Oilliol Oiuim, appointed in his will that the descendants of his two sons, Eogan and Cormac Oas, should sway the sceptre of the south in alternate succession. A very unwise proceeding, as future events proved.]

The first naming of these princes in the chronicle brings out an alliterative and patriotic glow on the pen of the enthusiastic chronicler.

"There were then governing and ruling this tribe two stout, able, valiant pillars, two fierce, lacerating, magnificent heroes; two gates of battle, two poles of combat, two spreading trees of shelter, two spears of victory and readiness, of hospitality and munificence, of heart and strength, of friendship and liveliness, the most eminent of the west of Europe, namely, Mathgamain and Brian, the two sons of Cennedigh, son of Lorcan, son of Lachtna, son of Core," etc.

Their cousins, the Eoganacht, having the lion's share in the government of Leath Mogha, the following were the principal privileges of the Dalcassians:

"It is the privilege of the host of Lugaidh's race
To lead the battalions of the hosts of Mumhain,
And afterward to be in the rere
In coming from a hostile land.
"It is not fealty that is required of them,
But to preserve the freedom of Caisel. [Footnote 281]
It is not rent, it is not tribute, as hath been heard;
It is not fostership nor fostership's fees.

[Footnote 281: The residence of the kings of the south assumed the title of Caisiol, (Cios, tribute, ail, stone.)]

"And even when there is not a king
Out of you over Erinn of hosts,
Only that you would not infringe on right,
No human power could prevail over you."

Early in their lives the princes entered on a skirmishing warfare with the enemy; and when Mahon, weary of the resultless struggle, entered on a truce with the enemy, Brian still continued to harass them, and as his zealous biographer says, when he could not injure them on any day, he did it next night, and every inactive night was followed by a destructive day. He and his followers lived in temporary huts, and continued to kill daily and nightly their enemies "by companies, by troops, by scores, by hundreds, and (in case of a bad day or night) by quaternions."

"Great were the hardship and the ruin, the bad food and bad bedding, which they inflicted on him in the wild huts of the desert, on the hard, knotty, wet roots of his native country, whilst they killed his people, and his trusty officers, and his comrades; sorrowful, wretched, unpitied, weary, for historians say that the foreigners cut off his people, so that he had at last but fifteen followers."
