The following passage is from the Book of Ballymote, and is supposed to be taken from the synchronisms of Flann of Monasterboice: "In the fourteenth year of the reign of Conaire and of Conchobar, Mary was born; and in the fourth year after the birth of Mary, the expedition of the Tain bo Chuailgne took place.

Eight years after the expedition of the Tain, Christ was born." The Four Masters have the following entry after the age of the world 5194:-- THE AGE OF CHRIST.
"The first year of the age of Christ, and the eighth year of the reign of Crimhthann Niadhnair." Under the heading of the age of Christ 9, there is an account of a wonderful expedition of this monarch, and of all the treasures he acquired thereby.

His "adventures" is among the list of Historic Tales in the Book of Leinster, but unfortunately there is no copy of this tract in existence.
