King Laeghaire died, according to the Four Masters, A.D.458.

The popular opinion attributed his demise to the violation of his oath to the Leinster men.

It is doubtful whether he died a Christian, but the account of his burial[136] has been taken to prove the contrary.

It is much to be regretted that persons entirely ignorant of the Catholic faith, whether that ignorance be wilful or invincible, should attempt to write lives of Catholic saints, or histories of Catholic countries.

Such persons, no doubt unintentionally, make the most serious mistakes, which a well-educated Catholic child could easily rectify.
