After this the sons of Milidh fought a battle at Taillten[58] against the three kings of the Tuatha De Dananns, MacCuill, MacCeacht, and MacGriene.

The battle lasted for a long time, until MacCeacht fell by Eiremhon, MacCuill by Eimheur, and Mac Griene by Amhergen."[59] Thus the Tuatha De Danann dynasty passed away, but not without leaving many a quaint legend of magic and mystery, and many an impress of its more than ordinary skill in such arts as were then indications of national superiority.

The real names of the last chiefs of this line, are said to have been respectively Ethur, Cethur, and Fethur.

The first was called MacCuill, because he worshipped the hazel-tree, and, more probably, because he was devoted to some branch of literature which it symbolized; the second MacCeacht, because he worshipped the plough, i.e., was devoted to agriculture; and the third obtained his appellation of MacGriene because he worshipped the sun.
It appears from a very curious and ancient tract, written in the shape of a dialogue between St.Patrick and Caoilte MacRonain, that there were many places in Ireland where the Tuatha De Dananns were then supposed to live as sprites and fairies, with corporeal and material forms, but endued with immortality.
