St Ita, also known as “Brigid of Munster,” was reputed of royal lineage. She was born about 475 in Decies, Waterford, Ireland. She refused to be married and secured her father’s permission to live a virginal life. She moved to Killeedy, Limerick, and founded a community of women dedicated to G-d. She also founded a school for boys, and one of her pupils was St. Brendan.
Many extravagant miracles were attributed to her (in one of them she is reputed to have reunited the head and body of a man who had been beheaded; in another, she lived entirely on food from heaven), and she is widely venerated in Ireland. She is also known as Deirdre and Mida.
Her austerities are told by St. Cuimin of Down, and many miracles recorded associated with her. She was also endowed with the gift of prophecy and was held in high veneration by a large number of contemporary saints.
When Ita felt her end approaching she sent for her community of nuns and invoked the blessing of heaven on the clergy and laity of the district around Killeedy.
Not alone was St Ita a saint, but she was the foster-mother of many saints, including St Brendan the Voyager, St Pulcherius (Mochoemog), and St Cummian Fada. At the request of Bishop Butler of Limerick, Pope Pius IX granted a special Office and Mass for the feast of St Ita.
St Ita died the 15th of January in 570.
