Sebastian Barry (born 5 July 1955) is an Irish playwright, novelist and poet. He is noted for his dense literary writing style and is considered one of Ireland's finest writers.Barry's literary career began in poetry before he began writing plays and novels. While he was once considered a playwright who wrote occasional novels, in recent years his fiction writing has been more successful than his work in the theatre.
He has twice been shortlisted for the Man Booker Prize for his novels A Long Long Way (2005) and The Secret Scripture (2008), the latter of which won the 2008 Costa Book of the Year and the James Tait Black Memorial Prize. His 2011 novel On Canaan's Side was longlisted for the Booker. In January 2017, Barry was awarded the Costa Book of the Year prize for Days Without End, hence becoming the first novelist to win the prestigious prize twice.
