Late-medieval Irish prose. These are three particularly tragic tales from Irish myth, which are often called The Three Sorrows of Storytelling. They deal with the death of whole families, namely the siblings:
Three sorrows of story-telling fill me with pity,
the telling of them grates on the ear;
the woe of the Children of Turenn--
sorrowful to hear.
And the Children of Lir, bird-shaped;
a curse on the mouth that told their doom:
Conn, Fiacra, Finola, and Aed--
the second gloom.
And the Children of Usnach, shield of men,
whofell by force and cunning craft--
Naoise, and Ainle, and Ardan...
There cracks the heart.
