Under this term we include both poets and chroniclers that is, the _Fileadh_ and the _Fer-comgne_.[17] Sometimes history and poetry are represented as distinct branches of learning in ancient Erin; it is certain, however, that in pre-Christian times, and long after the introduction of Christianity, the chronicler made poetry the medium of preserving and communicating to posterity both the genealogical and historical records of his tribe or clan. It is true, indeed, that the Introduction to the _Senchus Mor_ makes a careful distinction between the chronicler and the poet. "Until Patrick came, only three classes of persons were permitted to speak in public in Erin: a Chronicler to relate events and to tell stories; a Poet to eulogise and to satirize; a Brehon to pass sentence from precedents and commentaries." It is added that since Patrick's arrival, each of these professions is subject to his censorship; and it is noteworthy that no reference at all is made to the Druids after Patrick came to Erin, and this Brehon Code came to be purified. The commentator on the _Senchus_ also notes that for a long time the judicature had belonged to the poets alone, that is, from the time of Amergin, the first poet-judge, down to the time of the Contention at Emhain Macha between the two Sages, Ferceirtne and Neidhe. The language which the poets spoke on that occasion was so obscure, that the chieftains could not understand what had passed between the rival Sages. It was therefore ordained by Conchobhar (Connor) and his chieftains, that thenceforward the poets should be deprived of that exclusive privilege which they had hitherto enjoyed, and made too exclusive; and that the men of Erin in general should be entitled to have their proper share in the judicature. This dim tradition clearly represents a protest against the technical language of an exclusive and privileged class, who, for their own purposes, sought to keep secret their traditionary lore. Thus it came to pass that thenceforward the profession of the judge and poet became quite distinct, and the judge assumed the post of official chronicler and keeper of the records of his tribe. The function of the Bard, or poet, afterwards was 'to eulogize and to satirize;' and in this more restricted sense of the word the term poet or Bard is frequently employed in Christian times. We know, however, that as a matter of fact all our historical documents down to the tenth century are written in poetry, that is, in a certain metre and rhythm, which would help to preserve these compositions even without the aid of writing for the benefit of posterity; that is to say, the Chronicler was also a poet.
