Lays of Beleriand comprises of two long poems. One of them is the alliterative poem Lay of the Children of Húrin, the second one is the octosyllabic poem Lay of Leithien, i.e the story of Beren and Lúthien). Both of them are a valuable addition for a Tolkien reader. There can be found many passages of immense beaty as well as some weaker ones, partly deriving from the fact, that the poems are unfinished and so we have only a glimpse of what could be, if Tolkien had the life-span of a true Dunedain.
