On his return to Ireland he brawled and fought till he became king in 508.

He was married to a good wife named Duiseach, and had by her a family, but he fell under the fascinations of a beautiful woman called Shin, whereupon he turned away his wife; and--by the witchcraft, so it was supposed, of the witch--one after another of his children was carried off by disease, possibly by poison. Duiseach fled for refuge to S. Cairnech, who blessed her and all who would take up her cause, and gathered together a body of men resolved on fighting to replace her. Cairnech gave a book and his staff to be carried to battle before the host.

Now it happened that in a battle fought in 524 Murtogh had killed Shin's father and brother, and though the beautiful woman continued to exercise her blandishments on the king, she had vowed revenge in her heart against him. She awaited her opportunity. It came on the eve of Samhain, All Hallows, when high revelry was kept in the hall at Cletty, where Murtogh was residing. She had the hall secretly surrounded by her men, and herself set fire to it. Murtogh was very drunk, the fire caught his clothes, and, unable to escape by the doors, which were guarded, he threw himself into a vat of wine to quench the flames, and so perished, partly by fire, partly by wine, in 527.

It is possible--I cannot say more--that as this incursion, mentioned by the Irish writers, took place precisely at the period of the Brychan descent, it may refer to it, and that Brychan may actually have been Murtogh's half-brother, who accompanied him to Britain to carve out for himself a kingdom.

III. The third group is likewise Irish, but unmixed with Welsh elements. This consists of a swarm, or succession of swarms, that descended about the year 500 upon the Land's End and Lizard district.

Concerning them we know something more than we do about the second group.

Happily Leland, who visited Cornwall in the reign of Henry VIII., made extracts from their legends then in existence, very scanty extracts, but nevertheless precious. Moreover, we have one complete legend, that of S. Fingar or Gwinear, written by a Saxon monk of the name of Anselm. And we have the lives of many of those who made a temporary stay in the Land's End and Lizard districts, preserved in Irish MSS.

IV. A fourth group is that of saints, half Welsh and half Breton, who made a short stay in Cornwall on their way to and fro.

According to Celtic law, all sons equally divided the inheritance and principalities of their father. The consequence was that on the death of a king the most masterful of his sons cut the throats of such of his brothers as he could lay hold of. And as these little games were enacted periodically in Brittany, the breath was no sooner out of the body of a prince than such sons as felt that they had no chance of maintaining their rights made a bolt of it, crossed into Cornwall, and either halted there or passed through it on their way to Wales, where they very generally got married.

Then either they or their sons returned to Cornwall and lingered there, watching events in Brittany for the safe moment to go back and reassert their rights, and as they rarely could recover princely rights, they became ecclesiastics; a compromise was effected, and they were allowed to return and set up as founders of saintly tribes.
