Diarmaid Ó Súilleabháin (1932 – 1985) was an Irish language writer whose chosen theme was contemporary urban life.
[2] A story from Muintir called 'D' was translated into English and adapted for the stage by Vivian McAlister and was performed by Dublin University Players in May 1977.
[4] Like Eoghan Ó Tuairisc, he "challenged the critical orthodoxy by openly proclaiming that their standards could not be those of the Gaeltacht and by demanding a creative freedom that would acknowledge hybridity and reject the strictures of the linguistic purists.
His writing "explores the problem of recovering idealism and cultural wholeness in an increasingly shallow and materialistic Irish society.
[1][2] He wrote a collection of poetry, Cosa Gréine, which was published and launched in Dublin in 2013, 28 years after his death.
