A collection of 130-year-old photographs of the ten men accused of the Maamtrasna murders has been published for the first time.
The collection includes two pictures of Myles Joyce, a native Irish speaker, who was executed for his alleged part in the 1882 murders following a court case in English.
It is widely believed that he was not involved in the murder of the Joyce family.
The Maamtrasna case was described by British historian Robert Kee as "one of the most blatant miscarriages of justice in British legal history".
The photographs were collected by a former British army officer, whose grandson has passed them on to the National Library of Ireland.
The other images can be viewed on the website www.coimisineir.ie.
Coimisinéir Teanga Seán Ó Cuirreáin said the photographs "add poignancy and highlight the personal tragedies of the Maamtrasna case".
