Brendan the Navigator

Brendan of Clonfert (c. AD 484 – c. 577) is one of the early Irish monastic saints and one of the Twelve Apostles of Ireland. He is also referred to as Brendan the Navigator, Brendan the Voyager, Brendan the Anchorite, and Brendan the Bold. The Irish form of his name is Naomh Bréanainn or Naomh Breandán. He is mainly known for his legendary voyage to find the "Isle of the Blessed" which is sometimes referred to as "Saint Brendan’s Island". The written narrative of his journey comes from the immram Navigatio Sancti Brendani Abbatis (Voyage of Saint Brendan the Abbot).

Saint Brendan's feast day is celebrated on 16 May by Catholics, Anglicans, and Orthodox Christians.
