According to the "Trias Thaumaturga" Brigid spent time in Connacht and founded many churches in the Diocese of Elphin. She is said to have visited Longford, Tipperary, Limerick, and South Leinster. Her friendship with Saint Patrick is noted in the following paragraph from the Book of Armagh: ""inter sanctum Patricium Brigitanque Hibernesium columpnas amicitia caritatis inerat tanta, ut unum cor consiliumque haberent unum. Christus per illum illamque virtutes multas peregit"" ("Between St. Patrick and St. Brigid, the pillars of the Irish people, there was so great a friendship of charity that they had but one heart and one mind. Through him and through her Christ performed many great works.")
