The chief duty of the Historic Poet, or Chronicler, was to register the genealogies of the men of Erin, and to recite lays of battle, and rhymed stories or tales of Courtships, Voyages, Cattle-spoils, Sieges, Slaughters, and other moving incidents by field and flood. The Ollamh-poet, or Doctor of Poetry, was required by law to spend at least twelve years in careful preparation for his final degree, and to have prepared for public recitation seven times fifty tales or stories of the character already indicated. He was also required to be perfectly familiar with the pedigrees of the principal families, their topographical distribution, the synchronisms of remarkable events both at home and abroad, and the etymologies of names in Erin. He was besides required to know the artistic rules of poetry, and to have a knowledge of the seven kinds of verse and their various metres. It is evident that these manifold accomplishments required long and careful study; and the necessity of this training explains, what many persons think incredible, the wonderful accuracy of our ancient historical and genealogical records, which the evidence of facts now proves to be on the whole undoubtedly authentic and trustworthy documents. In the _Book of Ballymote_ there is a long list of great historians and poets, who flourished in ancient Ireland; many of them, however, are now known only by name. All our ancient records point to the fact that the Tuatha de Danaan, who colonized this country before the Milesians, were a people of considerable civilization. Their royal family seems to have possessed great culture. Daghda, the king, and his wife the Great Queen--Mor Rigan--are both represented as distinguished poets, who flourished more than 1,000 years before Christ. Diancecht, the royal physician, was also a distinguished judge and poet; his daughter, the princess Etan, was a poetess; and her son was no less remarkable for poetic talent. About the same period flourished the poet Ogma, the traditional inventor of the Ogham alphabet. The Milesians cultivated poetry with equal zeal. We have already referred to the poet-judge, Amergin, and we are told that a poet called Cir, and a harper named Ona, were amongst the first Milesian colonists. After the conquest of the country by the brothers Heber and Heremon, it was resolved to cast lots for the possession of these distinguished bards. The poet fell to Heremon and the harper to Heber, whence it came to pass that the Northerns were, in after times, distinguished for poetry; but the gift of music remained with their Southern brothers.
