which serve to illustrate our history, are so numerous, that it would be impossible, with one or two exceptions, to do more than indicate their existence, and to draw attention to the weight which such an accumulation of authority must give to the authenticity of our early history.

But there are two of these works which we cannot pass unnoticed: the CHRONICUM SCOTORUM and the ANNALS OF THE FOUR MASTERS.
The Chronicum Scotorum was compiled by Duald Mac Firbis.

He was of royal race, and descended from _Dathi_, the last pagan monarch of Erinn.

His family were professional and hereditary historians, genealogists, and poets,[18] and held an ancestral property at Lecain Mac Firbis, in the county Sligo, until Cromwell and his troopers desolated Celtic homes, and murdered the Celtic dwellers, often in cold blood.

The young Mac Firbis was educated for his profession in a school of law and history taught by the Mac Egans of Lecain, in Ormonde.
