Angus, The Dagda, Mananan the sea-god, enter not only into the sagas of the second cycle, but into those of the third, of the cycle of Finn.

And all along to the very end of the stories, and down indeed to the present day, the Tuatha De Danaan appear in various forms, slowly lessening in dignity and power, until they end in the fairy folk in whom the Irish peasants still believe.

They are alive and still powerful in the third--the Fenian--cycle of stories, some of which are contained and adorned in this book.

In their continued presence is the only connexion which exists between the three cycles.

No personages of the first save these of the gods appear in the Heroic cycle, none of the Heroic cycle appears in the Fenian cycle.
