Book excerpt: The sixth-century voyage of St Brendan from Ireland to America, is one of the most fascinating of all sea legends. Could the myth of the Irish monk and his crew sailing the Atlantic in a boat made of leather, nearly a thousand years before Columbus, have been reality? In 1976, Tim Severin and a crew of four men, set out to recreate the Brendan legend. Using the exact same methods in constructing their sailing vessel, they set out on their hazardous voyage, making it one of the most inspiring expeditions in the history of exploration.
