The Aengus in question afterwards killed the king, Crimthann, son of Enna Ceinnselach, to avenge his exile. In thirties and forties are the churches which he gave to Patrick in the east of Leinster, and in Ui-Cennselaigh, including Domnach-mor of Magh-Criathar and Inis-Fail, where Mochonoc and Mochatoc are, and Erdit and Augustin in the smaller island (but their shrines are in Sleibhte, since the place was occupied by Gentiles); Domnach-mór of Magh-Reta. Patrick was a Sunday here (i.e., in Domnach-mór of Magh-Reta), and they were on that Sunday building Rath-Baccain, the royal fort of the district. Patrick sent to prevent this, but no notice was taken thereof. Patrick said, "Its building shall be troublesome, unless 'offering' is done there every day." He also said that the fort would not be inhabited until the wind (gaeth) would come from the lower part of hell. This was Gaithini, son of Cinaed, who rebuilt the fort in the time of Fedhlimidh, and of Conchobhar in Tara.

After that Patrick had founded churches and establishments in Leinster, moreover, he left a blessing upon Ui-Cennselaigh, and upon the Leinstermen all; and he afterwards ordained Fiacc Find in Sleibhte, as bishop of the province.

He then went along Bealach-Gabhran, into the district of Ossory, and founded churches and establishments there; and he said that distinguished laics and clerics should be of them, and that no province should have command over them, whilst they remained obedient to Patrick. Patrick took leave of them afterwards, and he left the relics of holy men with them, and some of his people, in the place where Martar-tech is this day in Magh-Roighne. At Druim-Conchind, in Mairge, the cross-beam of Patrick's chariot broke when he was going to Munster. He made another of the wood of the druim. It broke immediately. He made one again, and it broke also. Patrick said that there should never be any implement made of the timber of that wood, which has been fulfilled, for even a pin is not made of it. Patrick's Disert is there, but it is waste.

Patrick went afterwards to the territory of Munster, to Cashel of the Kings. When Aengus, son of Nadfraech, got up in the morning, all their idols were prostrate; and Patrick and his people came to the side of the fort, and he (Aengus) bade them welcome, and took them into the fort to the place where Lee-Patrick is to-day. And Patrick after that baptized the sons of Nedfraech, and the men of Munster besides, and left a blessing and prosperity upon them. And he blessed the fort—i.e., Cashel—and said that only one race should be there for ever. And he was seven years in Munster. The learned calculate that he made an offering on every seventh ridge that he traversed in Munster.

When Patrick was baptizing Aengus, the point of the crozier went through Aengus's foot. Patrick asked, "Why was it that you did not tell me?" "Because," said he, "I thought it was the rule of the faith." "You shall have its reward," said Patrick; "your successors from this day forth shall not die of wounds." No one is King of Cashel until Patrick's comarb ordains him and imposes the grade on him. Patrick said:

"The sons of Nadfraech, of sounding fame,
Of them shall be kings and chieftains;
Aengus, from the lands of Feimhen,
And Ailill, his brother."

And twenty-eight kings, of the race of Ailill and Aengus, reigned in Cashel, ordained with the crozier, until the time of Cenngegan.

Patrick went after this to Muscraidhe-Breogain, and founded churches and establishments there.

One day he was washing his hands at a ford there, when a tooth fell out of his mouth into the ford. Patrick went upon the hillock to the north of the ford; and persons went from him to look for the tooth, and forthwith the tooth glistened in the ford like a sun; and Ath-fiaclai is the name of the ford, and Cill-fiacia is the name of the church where Patrick left the tooth and four of his people—viz., Cuircthe and Loscan, Cailech and Bedan. He bade them (i.e., the Muscraidhe) farewell, and left them a blessing.

He went afterwards to Aradha-Cliach until he was in Iochtar-Cuillenn in Ui-Cuanach; and Ailill, son of Cathbadh, son of Lughaidh, of the Eoghanacht of Airther-Cliach, met him. His wife went on the hillock where they (the clerics) were, and said: "The pigs have eaten our son Ailill through savageness," said she. And Ailill said: "I will believe if you resuscitate my son for me." Patrick commanded the boy's bones to be collected, and he directed a Céle-Dé of his people—i.e., Malach Britt—to resuscitate him. "I will not offend the Lord," said he. (He was seized with doubt.) Patrick said: "That is pitiful, O Malach! thy house on earth shall not be high; thy house shall be the house of one man." His house is in the northeastern angle of the southern Deise; its name is Cill-Malaich. Five persons can never be supported there.
