This oath was taken at Tara, where he had convened a general assembly, as had been customary with his predecessors at the commencement of each reign; but it was held by him with more than usual state.

His next act was to take a small portion of land from each of the four provinces, forming what is now the present county of Meath, and retaining it as the mensal portion of the Ard-Righ, or supreme monarch.

On each of these portions he erected a palace for the king of every province, details of which will be given when we come to that period of our history which refers to the destruction of Tara.

Tuathal had at this time two beautiful and marriageable daughters, named Fithir and Dairine.

Eochaidh Aincheann, King of Leinster, sought and obtained the hand of the younger daughter, Dairine, and after her nuptials carried her to his palace at Naas, in Leinster.
