The Voyage of Bran, Son of Febal, and His Adventure (Immram Brain maic Febail ocus a Echtra) is one of the most evocative of early Irish tales. Written around the eighth century ce, it tells of Bran's ocean voyage to an “otherworld” island sometime before the coming of Christianity to Ireland. Early Irish (Gaelic) tales of sea voyages to exotic islands were an established literary type known as jmmrama (“voyages” or, literally, “rowings about”). Typically in tales of this genre the heroes make an ocean voyage in a boat made of animal hide. They take with them a number of companions, some of whom are abandoned before the destination is reached. They encounter a number of exotic people and creatures on land and sea. These encounters often have a moral and sometimes an ironic character. Occasionally the travelers touch upon wider mythological or theological themes: the sovereignty of Ireland, the fall of Adam and Eve, the coming of Christ, and the events of the book of Revelation. At the end of the tale, the heroes return to Ireland to recount their adventures.
