Máire Mhac an tSaoi, Irish civil service diplomat, writer of Modernist poetry in the Dingle Peninsula dialect of Munster Irish, a memoirist, and a highly important figure within modern literature in Irish, is born Máire MacEntee in Dublin on April 4, 1922. Along with Seán Ó Ríordáin and Máirtín Ó Direáin, she is, in the words of Louis de Paor, “one of a trinity of poets who revolutionised Irish language poetry in the 1940s and 50s.” She has a lifelong passion for the Irish language and is one of the leading authorities on Munster Irish.
Mhac an tSaoi’s father, Seán MacEntee, is born in Belfast and is a veteran of the Irish Volunteers during the 1916 Easter Rising and the subsequent Irish War of Independence, and of the Anti-Treaty Irish Republican Army (IRA) during the Irish Civil War. He is also a founding member of Fianna Fáil, a long-serving TD and Tánaiste in the Dáil. Her mother, Margaret Browne (or de Brún) of County Tipperary, is also an Irish republican and a distinguished Celticist who teaches courses in Irish literature in the Irish language at Alexandra College and University College Dublin (UCD).
Mhac an tSaoi is influenced by her stays in the Dingle Peninsula in County Kerry with her uncle, Monsignor De Brún, at his parish of Dún Chaoin. Monsignor de Brún, similarly to his sister, is a distinguished linguist and Celticist, the literary translator of Homer, Dante Alighieri, Sophocles, and Jean Racine into Modern Irish, “and one of the most distinguished literary figures of his time.”
Mhac an tSaoi studies Modern Languages and Celtic Studies at UCD, before going to further research at the Dublin Institute for Advanced Studies and at the University of Paris. She writes the famous work of Christian poetry in Munster Irish, Oíche Nollag (“Christmas Eve”), when she is only 15-years of age.
Mhac an tSaoi spends two years studying in post-war Paris (1945–47) before joining the Irish diplomatic service and is working at the Irish embassy in Madrid when she commits herself to writing poetry in Irish following her discovery of the works of Federico García Lorca.
She remains a prolific poet and is credited, along with Seán Ó Ríordáin and Máirtín Ó Direáin, with reintroducing literary modernism into Irish literature in the Irish language, where it had been dormant since the 1916 execution of Patrick Pearse, in the years and decades following World War II. Her poetry draws on the vernacular spoken by the native Irish speakers of the Munster Gaeltacht of West Kerry during the first half of the twentieth century. Formally, she draws on the song metres of the oral tradition and on older models from the earlier literary tradition. In later work, she explores looser verse forms but continues to draw on the remembered dialect of Dún Chaoin and on a scholarly knowledge of the older literature.
Mhac an tSaoi is elected to Aosdána in 1996 but resigns in 1997 after Francis Stuart is elevated to the position of Saoi. She had voted against Stuart because of his role as an Abwehr spy and in radio propaganda broadcasts from Nazi Germany aimed at neutral Ireland during World War II.
In 2001, she publishes an award-winning novel A Bhean Óg Ón… about the relationship between the 17th-century County Kerry poet and Irish clan chief Piaras Feiritéar and Meg Russell, the woman for whom he composed some of the greatest works of love poetry ever written in the Irish language.
Her poems Jack and An Bhean Óg Ón are both featured on the Leaving Certificate Irish course, at both Higher and Ordinary Levels, from 2006 to 2010. Her literary translation of Rainer Maria Rilke‘s Duino Elegies from Austrian German into the Irish language is published in 2013.
Mhac an tSaoi marries Irish politician, writer, and historian Conor Cruise O’Brien in a Roman Catholic wedding Mass in Dublin in 1962. This makes her the stepmother to O’Brien’s children from his 1939 civil marriage. Her mother is deeply embarrassed by the exposure of the relationship and staunchly opposes the match, as she has long been a close friend of O’Brien’s Presbyterian first wife. Despite their subsequent marriage, the exposure of their extramarital relationship ends Mhac an tSaoi’s diplomatic and civil service career. They later adopted two children, Patrick and Margaret.
She then lives with her husband in New York City, where he becomes a professor at New York University (NYU) after the Congo Crisis destroys O’Brien’s diplomatic career. He is long blamed by the United Nations for the escalation of the Congo Crisis.
Mhac an tSaoi and her husband, who is then serving as Albert Schweitzer Professor of the Humanities at NYU, are both staunchly opposed to the Vietnam War. They are both arrested by the New York City Police Department (NYPD), along with Dr. Benjamin Spock and Beat Generation poet Allen Ginsberg, during an allegedly violent protest outside a United States military induction centre in New York City on December 5, 1967. Afterward, during an interview with The New York Times, she accuses the NYPD of using excessive force both during and after her husband’s arrest.
She later returns with O’Brien to live in Dublin, where she attends another protest rally against the Vietnam War along O’Connell Street in 1969.
Mhac an tSaoi dies peacefully at the age of 99 on October 16, 2021, at home where she has been cared for by her daughter Margaret.
