Brendan of Clonfert was one of those delightful early medieval historical figures like King Arthur–probably real, but with his achievements and journeys highly enhanced, elaborated, and embellished. His story ends up being sort of a medieval Gaelic version of Homer’s Odyssey.
Brendan sailed around the North Atlantic, in search of the Isle of The Blessed. Some have hypothesized that he may have been the first European to reach North America, before the Vikings and long before Christopher Columbus. Because of my own journeys, though, I am more taken with the notion that the Isle of the Blessed may have been the Faroe Islands.
