Previously unpublished poems by Seamus Heaney have been included in a new collection of his work available from today.
The Poems of Seamus Heaney contains over 700 poems in total, including all 12 of his collections released to date, and 25 previously unpublished poems.
Mr Heaney died on the 30 August, 2013.
Dr Rosie Lavan and Bernard O'Donoghue have worked for almost a decade to put together the collection, which is published by Faber and edited by Matthew Hollis.
Dr Lavan, an Associate Professor at the School of English at Trinity College Dublin, said they know Mr Heaney had been considering some of the unpublished poems for his collections.
Speaking to RTÉ's Morning Ireland, she said they all appear to be in a finished state, so they know he worked on them carefully.
"We also recognise that they're poems that relate to and complement poems that he did publish. They explore similar themes, familiar figures - his mother, for example," she said.
"So there are connections with poems that we already know, and yet these unpublished poems kind of extend our sense of Heaney and his writing career."
One of the 25 previously unpublished poems in the new collection is called Ribbons and is about Mr Heaney's two sisters.
Dr Lavan said it is one of her favourites and she loved it from the moment she read it.
She said it is an example of something Mr Heaney does so often and so well - providing a memory that is "immediately relatable".
"The memory of being at primary school, having a photograph taken. But of course, we also have a sense of him watching that and watching his sisters in that experience, many, many decades previously," she said.
"The poem was probably written in the late 1990s, but he's remembering a scene probably from the late 1940s or early 1950s, and because he's writing about a photograph of children, there's something particularly poignant about the way he's exploring memory in that poem."
