The Fairy Nurse
Andrew Lang, The Lilac Fairy Book
One of the earliest named Irish woman poets is Eibhlin Dubh Ni Chonaill
The story of Art O Laoire would probably have been forgotten long ago, but for the Caoineadh which was composed over his body at the Wake, by Eibhlin Dubh. Keening the dead, was an old tradition, and the Keen itself followed a well established pattern.
