A nation does not begin to write its history at the first moment of its existence. Hence, when the chronicle is compiled which first embodies its story, tradition forms the basis. None but an inspired historian can commence _In principio_. The nation has passed through several generations, the people already begin to talk of "old times;" but as they are nearer these "old times" by some thousands of years than we are, they are only burdened with the traditions of a few centuries at the most; and unless there is evidence of a wilful object or intent to falsify their chronicles, we may in the main depend on their accuracy. Let us see how this applies to Gaedhilic history. The labours of the late lamented Eugene O'Curry have made this an easy task. He took to his work a critical acumen not often attained by the self-educated, and a noble patriotism not often maintained by the gifted scions of a country whose people and whose literature have been alike trodden down and despised for centuries. The result of his researches is embodied in a work[1] which should be in the hands of every student of Irish history, and of every Irishman who can afford to procure it. This volume proves that the _early_ history of Ireland has yet to be written; that it should be a work of magnitude, and undertaken by one gifted with special qualifications, which the present writer certainly does not possess; and that it will probably require many years of patient labour from the "host of Erinn's sons," before the necessary materials for such a history can be prepared.
