fluenced by the view that some of the Tuatha Dé Danann had died as mortals, Dagda has long since passed away, and the mounds are places of sepulture, perhaps a reflection of the fact that kings were interred there. Yet they are apportioned by the chief survivors, Bodb Dearg and Manannan, the latter having the task of selecting concealed dwellings. These he found in beautiful hills and valleys, and drew round them an invisible and impenetrable wall, though the Tuatha Dé Danann themselves could see and pass through it.

Through Manannan's magic power Elcmar was expelled, and Oengus gained the síd, where he dwells invisibly, eating the swine and drinking the ale of immortality. In still another version a curious account of the
